Bug 292479

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:  I opened my laptop and restored it from the sleep mode by entering my password.  I then opened Thunderbird email to check and send emails. Thunderbird did not put a email in the TO: spot, just the name of the person.	

- Unusual behavior I noticed:
When in Thunderbird I tried typing the name of the person who I was sending the message too, normally Thunderbird would have found the name and put the email address along with it in the send to spot.  This time it came back with an error, ïnvalid email address, I then had to go back and reenter with just the email address to correct the problem to send the email.
- Custom settings of the application:
Thunderbird and Firefox were both in use when the crash seemed to happen although I had to restore my previous session of firefox from a OOPS error message, restore last session or not.  I chose to restore the last session and continue from the previous day.  All of the previous pages came back up with no problem and the computer seemed to be working fine until I noticed the lady bug in the Widget area.  I am not sure exactly what caused the crash, firefox or thunderbird.

The crash can be reproduced some of the time.

-- Backtrace:
