Description Rosetzky Cedric 2008-05-29 19:47:19 UTC 
Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          GCC-4.2.3 
OS:                Linux

As the title said, I tried to add the Device Notifier applet to the panel. I dragged it from the desktop to the panel, and the whole plasma crashed.

Backtrace:

Application: Plasma Workspace (plasma), signal SIGSEGV

Comment 1 Jonathan Thomas 2008-06-02 23:00:49 UTC 
I can reproduce this with KDE 4.1 Beta1.
Comment 2 Sebastian Sauer 2008-06-24 09:29:50 UTC 
can this still reproduced with beta2?
Comment 3 Rosetzky Cedric 2008-06-30 23:01:44 UTC 
Compiled from SVN today. This is still happening.
Comment 4 Bram Schoenmakers 2008-07-01 00:22:42 UTC 
Still reproducible, but with a completely different backtrace:

Comment 5 Alex Merry 2008-07-05 13:19:18 UTC 
What Qt are you using?  4.4.0 from you distro, or qt-copy?
Comment 6 Rosetzky Cedric 2008-07-05 21:48:12 UTC 
Debian's QT 4.4.0.
Comment 7 Aaron J. Seigo 2008-07-07 01:20:19 UTC
