Application: rekonq (0.8.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-24-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

There was an Synaptiks error box at the start of Kubuntu with a link to report a bug!Then i clicked on it! But i don't really know when the crash occured (when i clicked the link? when i exit Rekonq?)
I've got no touchpad!
- Unusual behavior I noticed:

When Kubuntu starts an error message concerning synaptiks (tablette tactile) appears and a possibility to report bug! Then i trued to launch synaptiks again with no success... always this box with error explanation and a link to report the bug!

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
