KGpg (kgpg), signal: Segmentation fault

[starslights]

Binary package hint: kdeutils

Hello,

i run Kubuntu Karmic 9.10 x86 64 and since the final release, kgpg make some crash with a seg fault.

Application: KGpg (kgpg), signal: Segmentation fault
[KCrash Handler]
#5 0x000000000043c623 in _start ()

i have added dbg but it refuse to send the rapport it's own.

Ces informations de plantage ne sont pas suffisantes, voulez-vous essayer de les améliorer ? Vous devrez alors installer quelques paquetages de débogage.

I have added it but no diference

best regards

Hi,

I had kgpg end after a segmentation fault as well. It happened and then when I restarted the program, it said that gnupg was running an agent that was interfering with the function of kgpg. I edited the ~/.gnupg/gpg.conf file and commented out the line that said "use-agent" and then it worked better (and had less exits because of segmentation faults).

Because I was still having problems, and the bug report was said to not be useful, I downloaded valgrind and followed the how-to located here: https://wiki.kubuntu.org/Valgrind

I put the valgrind.log file in a .tar.gz archive as recommended in the article and I attached it to this post. I'm not knowledgeable enough to be able to judge for myself whether the log file will be useful or not but I hope that it is.

Sorry, I forgot to mention... I am running Xubuntu Karmic Koala 9.10. Kernel 2.6.31-16-generic with an Intel(R) Core(TM)2 Duo CPU T8100 @ 2.10GHz. Unlike the previous user who had issues with a segmentation fault, mine was not on an x64 processor.

Several people, also other bug reports (duplicates)

I trigerred the crashes mostly with:
Adding / deleting key with import-key (it was an RSA type key)
and/or refreshing the window

Hi,

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!

Hello Jonathan,

I have open a bug by KDE and post link here for others users who want add infos:

https://bugs.kde.org/show_bug.cgi?id=221666

Best Regrads

[LimCore (limcore)]

This happens all the time.

I don't see why we close bug here?

More info: it seems to crash on boxes that have several keys etc, not so much on clean installs that so far do not have opnepgp keys or just 1 or 2.

Current Kubuntu bug policy is to only track packaging bugs at Launchpad. Tracking a bug that's already being tracked at KDE is pretty much useless, as the fix will always be incorporated in the next release.
