Bug 258423

Version:           unspecified (using KDE 4.5.80) 
OS:                Linux

The KDE Daemon crashes every time I log in. This didn't happen with 4.5.x versions.

Trace from the Crash Reporting Assistant:

Application: KDE Daemon (kdeinit4), signal: Segmentation fault

Reproducible: Always

Steps to Reproduce:
Log in. This probably requires a Wacom graphics tablet since the device is clearly mentioned in the crash log.

Actual Results:  
The KDE Daemon crashes.

Expected Results:  
The KDE Daemon does not crash.

A graphics tablet "Bamboo Pen" is installed but not plugged in.
