Description George Dvorak 2012-04-09 08:10:19 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-22-generic-pae i686
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I changed the Time Zone in the Adjustable Clock Widget
- Unusual behavior I noticed:
Clicking OK causes the screen to go black.
- Custom settings of the application:
These are my Source settings: <html><head></head><body><div style="text-align: center; margin-top: 1px; margin-right: 1px; margin-bottom: 1px; margin-left: 1px; white-space: pre; font-size: 24px; "><font face="Ubuntu" color="#007f00"><b>%I:%M:%S %p</b><span style="font-size: 29px; ">
</span><small style="font-size: 18px; ">%a</small><span style="font-size: 18px; "> %e</span><span style="font-size: 18px; "> %b, %Y</span></font></div><div style="text-align: center; margin-top: 5px; margin-right: 5px; margin-bottom: 5px; margin-left: 5px; white-space: pre; font-size: 11px; "><small style="font-size: 11px; "><font face="Ubuntu" color="#007f00">%g (%Z) UTC %z</font></small></div>

The crash can be reproduced every time.
