opensuse 11.0 x86
Qt: 4.4.3
KDE: 4.1.71 (KDE 4.1.71 (KDE 4.2 >= 20081023)) "release 5.1"
Akregator: 1.3.50

i recently upgraded kde from 4.1.70 to 4.1.71 and now akregator crashes as soon as it's window tries to open. here is the output:

Object::connect: No such signal Akregator::SubscriptionListView::signalContextMenu(K3ListView*,Akregator::TreeNode*,QPoint)
Object::connect: (sender name: 'feedtree')
Object::connect: (receiver name: 'akregator_view')
Object::connect: No such signal Akregator::SubscriptionListView::signalDropped(KUrl::List&,Akregator::TreeNode*,Akregator::Folder*)
Object::connect: (sender name: 'feedtree')
Object::connect: (receiver name: 'akregator_view')
echoes@echoes:~> KCrash: Application 'akregator' crashing...
sock_file=/home/echoes/.kde4/socket-echoes/kdeinit4__0

is anyone else experiencing this and does anyone know a possible solution?

When you upgraded KDE to 4.1.71 did you update akregator at the same time?
If you didn't well then there is your cause. Alternatively you could try removing / moving the config file ( akregatorrc in ~/.kde4/share/config ) and trying again.

yes i did upgrade akregator along with the upgrade to 4.1.71.

removing the config file totally slipped my mind. i tried it, but unfortunately it didn't make a difference.
i also tried reinstalling akregator but that didn't work either.[hr]
is it possible to run akregator from command line? what i mean is, does akregator have a command line client/interface?

I just checked my akregator. It appears that the "Object::" things also affect me, although my akregator does load. Comparing them however i have two more than you.

Code: Select all

Object::connect: No such slot Akregator::ArticleListView::slotPaletteOrFontChanged()
Object::disconnect: Unexpected null parameter


You may want to ( assuming you are using build service packages ) update the akregator package again, because it may have already been fixed, and if that fails contact it's developers.

good to know it isn't just me. (as weird as that may sound).

i am not using build service packages.

i assume from what you said that you are using opensuse too?

I use build service packages for everything i can. Yes, I also run openSuSE but I use KDE 4.1.2, if you just want to follow the progress of trunk then you should use the KDE:KDE4:UNSTABLE repository. You could also try removing the ~/.kde4/share/apps/akregator folder ( which is a cache of all posts it has downloaded, the format may have changed / your cache may be corrupt )

no such luck. renamed the folder & launched akregator again but the same problem. :'(

Failing everything, you could svn up just akregator and recompile it. it sounds like you just hit a time where the developers were in the middle of making changes ( grasping straws here.. ).

Also check to make sure you are using the right versions of the libraries the akregator needs.(They may be close enough to compile, but too far apart to work)

Today I recompiled my svn KDE with kdesvn-build and Akregator came back to rock!
In the times it didn't worked, I used it by launching Kontact and using its Feeds tab, which loaded the KPart of Akregator.

not that i can't compile anything, but i think i'll wait till kde 4.1.71+ hits opensuse.

here is what happened when i tried a backtrace, but it didn't produce anything of worth afaik:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

UPDATE:

FYI, kde 4.1.72 does indeed fix this problem.

Good to hear you managed to resolve your problem. Please mark the thread as solved ( edit the subject to include [SOLVED] at the start )

Argh, this has hit me now! Started after a system breakdown (my RAM is dodgy, ran memtest overnight and got 12 errors )

I've tried reinstalling akregator and kontact but no joy as yet. All the other kontact modules work okay.

Toad: try removing $(kde4-config --localprefix)/share/apps/akregator
Note that this will likely erase your feed configuration.

Cheers for the feedback - for some reason I didn't get notified, so that is why a) I didn't follow your advice and b) I am answering late

I managed to get it sorted by removing the akregator directory from ~/.kde4/share/apps and it worked again, ergo: some data was corrupted. Turned out it was the BBC news that got corrupted and threw akregator. Took some investigation and I lost all 7000 news entries, but they are amassing again nicely

Once again, thanks for replying.
