Description Tristan Miller 2009-02-26 15:12:18 UTC

Version:            (using KDE 4.2.0)
Installed from:    SuSE RPMs

I was working in KDE normally when Plasma crashed with a SIGSEGV.  The last thing I did before the crash (which may or may not have anything to do with it) was clicking the minimize button in the title bar of a window.  The window was an application running remotely via Nomachine NXclient.

Backtrace:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Comment 1 Dario Andres 2009-02-26 21:34:34 UTC

If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? 
You need to install the "libqt4-debuginfo" package.
Thanks :)

Comment 2 Tristan Miller 2009-02-27 01:27:03 UTC

Sorry; it's the first time Plasma has ever crashed for me, and the problem hasn't reoccurred since, even though I've been doing much the same things.  If this bug report isn't useful as-is, feel free to close it.  I'll provide further details as requested if the problem ever becomes reproducible.

Comment 3 Tristan Miller 2009-02-27 14:23:38 UTC

Here; it's just crashed again while clicking on the titlebar of a locally running application.  I'll install the libqt4-debuginfo package and follow the tutorial in case it happens yet again.
