Description Jens Staal 2008-10-16 10:47:59 UTC

Version:           kded4 (using KDE 4.1.2)
OS:                Linux
Installed from:    SuSE RPMs

KDE daemon (kded4) crashes at occasions. I have not seen any pattern in loaded apps or anything like that. I am using OpenSuse 11.0 x86_64.

After this crash, the window management is messed up, but not in a critical way.

This might be a replicate of two previous bug reports, but they were dealing with earlier versions of KDE.

The crash message is as follows:
Application: KDE Daemon (kded4), signal SIGSEGV

Hello Jens,

unfortunately, the backtrace is not useful.
Please get a better backtrace, you can find more instructions in the page:
http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Comment 2 David Faure 2008-10-16 20:01:47 UTC

Probably the inotify crash or the globalaccel assert though...

Comment 4 Dario Andres 2008-12-19 14:15:29 UTC

Backtrace in comment 3 looks like the one in bug 165548. (I don't know if this is related to the original bug report)

Comment 5 David Faure 2008-12-24 14:23:40 UTC

Yes, comment 3 is bug 165548, while the initial report is impossible to file properly (backtrace has no info). Closing for now, Jens, please reopen if you get the crash again and you installed debug packages first ;)
