Description Alex Merry 2010-05-28 11:03:33 UTC 
Version:           unspecified (using Devel) 
OS:                Linux

Plasma from 4.5 trunk (r1130846) crashes on logout.  This always happens if I've been using the desktop for a while first, but doesn't always seem to if I just log in a straight back out again.

Reproducible: Always

Steps to Reproduce:
Log in, work for a while, log out (or shutdown).

Note that `kquitapp plasma-desktop` does _not_ seem to cause the crash.

Actual Results:  
Crash!

Expected Results:  
No crash.

I reset the plasma configuration when I started following trunk about a month ago, so it's not a strange configuration hangover from 4.4.

fixed in trunk
