Bug 263192

Application: ksysguard (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-server x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Trying to create a new tab (didn't get very far this time; I've got farther before). i had just copied a new Process table into a new tab I'd just made.
- Unusual behavior I noticed:
After I searched for 'table', I chose the default process table, by clicking and dragging it into the new, empty window frame on the left. This is when it gets weird.
The process table appeared as a mini-process table at the top left of the window, and another process-table behind it covering the remaining of that window frame. The original first tab usually holding the process table is now blank.
- Custom settings of the application:
None; this was my first tweak to ksysguardd since installing this version of kubuntu through debootstrap.

The crash can be reproduced every time.

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