[KDE 4] kded crashed

[Alexander Rødseth]

I don't know how to reproduce this.
I was running the KDE4 "konsole" and "lastfm" (uses Qt), but the crash happened when I was on another desktop and in another application.

Here's the backtrace:

Has this occurred more than once at all? I will research upstream and other bug sites to see if there was anything similar reported. Thanks!

[Alexander Rødseth (alexanro)]

AFAIK, this has only happened once. I get so many backtraces from KDE 4 that I'm unable to remember them all.

kded4 crashed again. The only KDE-application I was running was kmix. (kmix/kde4)

I was watching a video in Firefox when suddenly the crash-window appeared, telling me kded4 had crashed.
Seems like it's the same line of code as last time, even though this backtrace is different.

Looking at the code of kdirwatch.cpp I think the issue got fixed in 4.1.

Please reopen this report if the creash reappears.
