Application: digikam (3.1.0)
KDE Platform Version: 4.9.5 (Compiled from sources)
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:
I clicked the "perspective correction tool" button with a CR2 image in the light table.
Digikam compiled from sources, all dependencies from the Mint 14 distribution.
I'd be happy to provide whatever addition information may be of use.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
