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

Followed same process within Aquire Images (scangui) and XSane. I aquire a preview, then select an area near the bottom right corner. When I click to scan the app crashes. I am scanning using a HP Deskjet 1050. Happens every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Acquire images (scangui), signal: Segmentation fault
