Bug 130634

That backtrace says nothing at all. Is the crash reproducible? Do you have a specific file that provokes the crash? If so, can you attach it to the bug report?

The crash is reproducible, it happens anytime I open up kate and then when closing it, it crashes. I hadn't tried using only certain files, I had 7 open so I closed them one by one, closing kate after each one and it still crashes with only the default blank untitled open. I have a few other applications open like kopete, skype and thunderbird which i also shut down and tried out kate and it still seems to be crashing everytime i close it. I don't know what other info I could give you that could help?

If you could get a hold of a build with debugging symbols, you will get a much more useful backtrace. I have no experience with Fedora, but I assume they have debuggable packages available somewhere.

Yup, it's easy with Fedora.  Every package has a -debuginfo counterpart, so just yum install kdebase-debuginfo and you should be set.

pic of stack window when debugging kate

I tried debugging using KDbg and the only window showing any changes when cosing was the stack window, i've included a screeshot of this window. Is there any other info i could get?

Well the problem seems to have stopped now. I updated a few packages on my system this morning and kate seems to have been fine all day so can this be marked as resolved? Thanks to everyone for their help.

See above comment.

Hey, I have the same problem. I'm using archlinux's pacman binary.

b5f3c000-b5fKCrash: Application 'kate' crashing...

matt@megabyte:~$

----------------
I've done a lot of googling and searching for this bug, and somebody in kubuntu's IRC (Tm_T) wrote that he thought it was a libc issue. I'm not sure how to get a debug version of kate without compiling the entire KDE source, so this is all the info I have. Sorry to open the bug again, but I've had this bug for a long time, through several pacman updates.

Matt

Oh, I forgot to mention that only kate crashes. Kontact and even kwrite are perfectly fine. Sorry if the previous post was too long, but I'm not sure where to put that crash output.

it's fixed, see bug #147195. so repoen + mark as duplicate
