When I try to launch kdirstat from Lancelot, it launches Kate instead. If i use the standard K launcher, it gets it right.

Right-clicking on the launcher and looking at the Menu Editor gives the correct entry. It looks like Lancelot uses the same config file as the K launcher.

Ideas? TIA.

Also, I see examples where there are just icons with very small names under them in the K launcher window. I see a list with icons to the left. How to change?

Using Kubuntu 10.04 Lucid Lynx with KDE 4.4.2.

Here are some trouble-shooting questions:
1. Does it happen only for kdirstat->kate, or for something else as well?
2. Does it happen always or just sometimes?
3. How do you launch it - via search, or are you browsing to get to the kdirstat?

You can do the following to additionally help:
1. Open config window and make sure logging (usage statistics) is on
2. Launch KDirStat
3. Post here the last lines of the last modified file in .kde/share/apps/lancelot/log/
(the name will be log-2010-6 if you do that this month )

Thanks for your reply.

Here's the end of the log:

If I click on the Kate entry, it opens Kate with the files I last had open. When I click on the Kdirstat button, it opens Kate with an empty file called kdirstat.desktop. But if I look for it in my home directory with

$ find . -name kdirstat.desktop

no such file is found.

Ok, the problem is that it can't find the desktop file, so it doesn't know that it /is/ a desktop file and can't execute it.

Where is kdirstat.desktop located in the system?

Don't know why it would want to execute it, but ...

Where is kdirstat.desktop located in the system?

$ find . -name kdirstat.desktop 2>/dev/null
./usr/share/applnk/Utilities/kdirstat.desktop

What purpose does this file serve and who/what put it there?

$ ls -l /usr/share/applnk/Utilities/kdirstat.desktop
-rw-r--r-- 1 root root 515 2008-02-12 05:14 ./usr/share/applnk/Utilities/kdirstat.desktop

"Don't know why it would want to execute it, but ..."

When I say /execute/ a .desktop file, I mean, execute the application specified in Exec part of it (like executing a shell script which in turn executes some other program)

So, it is in a strange location which lancelot doesn't search for some reason*.

Can you test the following, open konsole from the normal launcher and type
killall lancelot
lancelot

When it starts, try starting KDirStats again. Does the same thing happen?


* what is strange about it - L uses the *same* mechanism as all other app launchers in KDE - it is rather strange to see that it starts in one and not in the other...

Yes, same result. So why does it work with the K default launcher? Hmmm...

After stopping it (ctl-C), I see processes which were not there before:

$ ps -edf | grep lancelot
jon 6405 1477 0 14:12 ? 00:00:00 kdeinit4: kio_file [kdeinit] file local:/tmp/ksocket-jon/klauncherMT1482.slave-socket local:/tmp/ksocket-jon/lancelotPE6403.slave-socket

Ok, I've just pushed a /fix/ that will be in 4.5.

Since I can't test this, I can't really say it is a fix, but it was the only weak-spot I noticed in the code, so I hope it will fix this address issue.

Just another question, I'm a bit curious - if you right-click the KDirStats and add it to Favourites:
0. It doesn't add anything
1. It is placed in Favs, but doesn't work
2. It is placed in Favs, and it works

2a. Something is added to Favorites, But instead of being "Kdirstat - Directory Statistics" with a pretty icon, it's just "kdirstat.desktop" with a greyed-out gear wheel.

Can I get this to work by deleting or moving the kdirstat.desktop file?

> Can I get this to work by deleting or moving the kdirstat.desktop file?

Most probably, if it is moved to the place the rest of items reside in.

I would also recommend checking under ~/.local and ~/.kde for any "kdirstat.desktop" files.

Also, try running "kbuildsycoca4 --noincremental"

I tried "kbuildsycoca4 --noincremental", but it didn't help. I can send the output of that if you like.

I did a "find" for all *.desktop files and they are all over the place. Many seem to be in /usr/share/applications, so I copied the file there and erased (well, renamed it) in the old location. I killalled lancelot and restarted it, but the problem persists.

When I do a "save as" in Kate to try to find where it is getting the file, it says it is in ~/Utilities, but this directory does not exist.

So I have no idea what to do except wait for the fix.

Thanks for you help.

can you post the contents of the file here?

Also, I made a small mistake. When I really deleted the file kdirstat.desktop, the Kdirstat entry disappeared entirely from Lancelot's menu. Also from Klauncher's.

Just want to confirm simular behavior with maxemum TV-Guide. Lancelot opens the maxemumtvguide.desktop in kate instead of the application.
