Sentry Crash Report:

Description romuluspb 2013-05-02 21:54:56 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

I was conecting a second display to my Dell XPS L502X with kubuntu, my note work with fullHD resolution and the display is a samsunhg with 1680x1050.
The second display was configured to apear to the right of the first one.
When it showed de plasma desktop I found the misbehave of painels positions and tried to configure so, widgets where unlocked at the time, but when I tried to configure one of the panels it did not responded.
I was going to do a xkill when KDE crash report appeared.

- Unusual behavior I noticed:

When the display was detected, all pannels were aligned to the left on it, and there existed a second one on the bottom, over the first, by what I could see.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted

XIOError, without other threads using X. Most probably a bug in X server or libraries.
Comment 2 romuluspb 2013-05-09 03:34:58 UTC 
Now Im having more contact with the new system version I noticed some things clearer, maybe it can help:

.Some times Xorg start to use a core completely and system interface go slow... Need to restart session.
.All times I plug a monitor plasma-desktop becomes unresponsive and it shows, on the new screen, duplicated plasmoids, by what I can say, translated to the origin zero point of the screen (everything is to the left down)

It appear plasma try to completely set the new screen but it is frozen in the middle of the process...
Comment 3 Martin Flöser 2013-05-30 07:24:04 UTC 
Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid. 

Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times. 

If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
