Sentry Crash Report:

Description Peter Nichol 2016-04-04 00:04:43 UTC 
Application: scangui (4.6.0)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-29-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: scanning glass plate negatives using AquireImages programme, the transparency selection with 2400dpi, colours inverted and greyscale

- Unusual behavior- I noticed: the scan finished much quicker than it should have done. The image produced was only a small section of the negative selected. This has happened at least a dozen times.
System is OpenSuse v 13.2

The crash can be reproduced sometimes.

-- Backtrace:
Application: Acquire images (scangui), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
