Bug 271025

Application: ksysguard (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Linux Mint 10 Julia

-- Information about the crash:
- What I was doing when the application crashed: Attempting to change scale on a voltage graph with multiple voltage sensors. Graph originally contained disk temp readings; reducing scale to 0-12v range down from a max of 60.

The crash can be reproduced some of the time.

-- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
