My report (maybe to do with cookies?) was not accepted by KDE bugs for whatever reason so I am including the report in this filing.

Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-40-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
- viewing a web page in Firefox
- sorry there is nothing else to report

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
