Description David Smith 2012-09-29 04:59:58 UTC

I think this is different from the other screensaver configure crash since this appears to be caused *ONLY* by permissions issues.


The workaround is to just not run it with elevated privileges.

Crash dump generated by steps above:

 Application: KXSRun (kxsrun), signal: Aborted

Using host libthread_db library
"/lib/i386-linux-gnu/i686/cmov/libthread_db.so.1".

Reproducible: Always

Steps to Reproduce:

1. Edit your "System Settings" menu item: select "run as different user"
2. Start up System Settings, it prompts for root password, enter it.
3. Click on "Display and Monitor"
4. In the window that pops up, click on "Screen Saver" on the left.
5. Expand one of the screensaver selections in the middle of the screen.
6. Click a screensaver.
7. Segfaults.

Actual Results:  
Crashes

Expected Results:  
The screensaver should be configured properly.
