Application that crashed: kontact
Version of the application: 4.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was viewing Facebook on a tab in Akregator (after opening it from an RSS feed). I was playing Lexulous, a flash game. (As a side note, this game didn't used to work in Konq or Akgregator, and I had to use Firefox... I don't know whether a Flash or KDE update fixed it, but thank you to whoever it was! Anyway...) I right-clicked the page and selected Reload, and Kontact immediately crashed. Facebook was the only tab open, besides the default tab showing the contents of the selected feed.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
