Hey all, using pclinux os 2010 beta2, kde 4.4.1, dolphin 1.4
I'm able to get previews of my .cbz. But no previews of .cbr.
Unrar is installed. The system has no problems extracting .cbr files.
I also have no problems viewing the same .cbr files in Qcomicbook.
Just no preview thumbs on .cbr files in dolphin.
Thank you for your time.

Try increasing "maximum file size" value in Dolphin preferences (General->preview).

Thank you for your quick reply.
O.K. I maxed out my maximum file size to 100mb -- still no previews on .cbr

Can you use cbr files in okular?

That seems to be the problem. Okular can preview .cbz comics, but not .cbr comics. It says "cannot open document, unrar not found" But unrar 3.93 is installed, to test this I extract these same .cbr files in Ark, no problem. The exe is in /usr/bin.
Could Okular be looking in wrong directory ??

It may also be a problem with your distribution. Do you have a link to some cbz and cbr files (free ones of course) that I can use to see if it works on my system?

This should be solved soon.
I submitted a bug report to kde, the developer of Comic Book Thumbnailer for KDE 4, Harsh J emailed me today and said he changed the source code on svn. Take a look here:

Thanks for your help TheBlackCat

Maybe, but considering the path where it's located it seems unlikely. It really should find unrar when it's in such a common location.

The unrar I have installed is 3.90 beta3, and I have only .cbr files to test with but with that version in /usr/bin it works as it should.

Two things you could try:

1. Copy/link unrar to another location in your path (/bin for example) to see if it's a path-problem.
2. If possible, install an earlier version in case the expected behavior of unrar has changed and the error-message is wrong (this one seems unlikely).

Got another email from Harsh J from bugs.kde.org said it was now fixed and will be included in kde 4.4.2
But for 4.4.1. I tried to copy/link unrar to /bin - no joy. Not really sure what else to try.
If I do a which unrar
The output is /usr/bin/unrar
and if I do a unrar | grep UNRAR
I get no output
and from terminal if I enter unrar
The banner shows:

I think that's the problem. According to the svn-link, the current version of the plugins look for "freeware" in the output. If that string isn't found, or a rar executable is named unrar, the plugins don't work as they should. Had you had the freeware version installed instead it would have worked.

O.K. I completly removed my rarlinux, and installed rarlinux-3.3.0. Now my unrar | grep UNRAR shows
UNRAR 3.30 freeware Copyright (c) 1993-2004 Eugene Roshal
It has fixed Okular, which can now view .cbr
But still no .cbr thumbs in Dolphin
It installed to /usr/local/bin. So I copied the 2 exe's (rar and unrar) to /usr/bin.
Still no .cbr thumbnails in Dolphin.
Wow, this is driving me crazy

It is possible that the previewer isn't implemented for *.cbr files at this time.

Make sure it is enabled in Dolphin > Settings > Configure Dolphin first though.

It is. Well, either that or my system is very confused...in other words, it works for me.

Yes, the previewer is implemented for .cbr files. Harsh J tested it using trunk, and said it worked for him. It seems to be a problem with pclinuxos 2010 beta 2. Isn't there something I can do with trunk svn on this system, without having to recompile the entire kdebase/runtime? (I also do know what I'm doing as far as the settings go. I use slackware13 with kde 4.2.4 and have installed the comicbook thumbnailer plugin 0.1 from kdelook.org, and it works perfect in my slackware, and I am using the same folder with the same files)
Thanks for your time guys
