Description Timo R. 2009-12-14 22:19:45 UTC 
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-gentoo x86_64

What I was doing when the application crashed:
Well, whenever i plug in my usb-memory-stick(Does not matter which one, any stick causes the crash), i get this crash.
It does not matter of the Device Manager(the one that displays recently plugged in devices) is in the taskbar or not.

Comment 1 Anne-Marie Mahfouf 2009-12-15 18:26:21 UTC 
Timo can you post a better backtrace please?

Maybe have a look at https://bugs.kde.org/show_bug.cgi?id=209582

KDE 4.3 is untested with Qt 4.6 by the way. You will want to check 4.4 beta 2 which will be out soon to see if this bug is still present.
Comment 2 Timo R. 2009-12-16 13:54:40 UTC 
Here are two backtraces, one for plasma-desktop, and one for kdeinit4, which crashed this time, too:

Comment 3 Dario Andres 2009-12-18 15:58:17 UTC 
From bug 219190:
----
What I was doing when the application crashed:
I resume my machine from sleep, and error happens. I think it only happens on
first suspend/resume cycle after reboot.

I have a Lacie 500GB external USB drive connected to the computer that doesn't
get powered off or suspended

Seems like a solid bug
Comment 8 Alex Fiestas 2013-03-03 15:34:53 UTC 
I remember fixing something similar during 2011.

Alberto can you reproduce this? anybody can? should we close it?
Comment 9 Andrew Crouthamel 2018-09-04 15:43:17 UTC 
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Please try again with the latest version and submit a new bug to frameworks-solid if your issue persists. Thank you!
