Bug 297840

Application: partitionmanager-bin (1.0.3)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
Successfully restoring a backed up file system to an _existing_ partition crashes the application after hitting "OK" in the progress dialog.

Apparently, the overwritten partition object is deleted twice, it appears.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Partition Manager (partitionmanager-bin), signal: Segmentation fault
