Application: digikam (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-35-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1. I tried the liquid rescale tools with really small Width / Height values.
2. Unsatisfied with the results, I pressed Cancel
3. I tried again, but noticing that part of the UI was obscured, I tried dragging the right border of the image slighly to the left, in order to make the UI wider. Then it crashed

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