Bug 288655

Application: python2 (0.7.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Booting up; no interaction with system other than entering kwallet password

- Unusual behavior I noticed:
Touchpad remained disabled; did not become enabled when ext mouse removed; ext mouse not usable on plugging in again until I restarted synaptiks (this is probably logical behaviour, not unusual)

- Custom settings of the application:
Automatically start at logon (has previously booted without crashing)
Automatically switch off touchpad if mouse plugged in
Automatically switch off touchpad on keyboard activity

-- Backtrace:
Application: synaptiks (python2.7), signal: Segmentation fault
