Looks like a corrupt KDE icon cache. Don't ask me why it sometimes happens, but the icon cache sometimes goes corrupt. It's kdelibs' fault and not Kompare's, not that it changes all that much for you. Try deleting the ~/.kde/cache-*/icon-cache.kcache file.
Whoops, nevermind… Looking at the full backtrace, this is NOT the icon cache's fault, but infinite recursion at komparenavtreepart.cpp:674 inside Kompare.
Can you please attach the input files which cause this bug (or e-mail them directly to me if you don't want them public)?
What files are those, and where do I find them?
What diff/patch file did you open, or what files did you compare?
I have no clue at this time.
That's too bad. :-( The source of the crash is that somehow, in the directory tree view, a folder ends up being its own child, or at least the recursion that walks the directories incorrectly thinks so. So I wonder how this can happen, the input file would have helped a lot. :-( Please let me know if you see this happening again. I'll try to figure out anyway what's going on, but without the reproducing diff, it's going to be hard, unfortunately.
I'll watch for it again.
I can reproduce the crash at will. I tried to compare Qwt 6.1.0 source bundle with SVN version and it crashes. To reproduce, download qwt-6.1.0.tar.bz2 from http://sourceforge.net/projects/qwt/files/ and then do svn checkout from: svn checkout svn://svn.code.sf.net/p/qwt/code/branches/qwt-6.1 Extract the first archive and then use Kompare to compare the two directories. For me, kompare shows the message box "The diff is malformed. Some lines could not be parsed and will not be displayed in the diff view." before crashing. My setup: KDE 4.11.3 Fedora 19, x86_64
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
