Application: skanlite (0.7)
KDE Platform Version: 4.6.5 (4.6.5) "release 5"
Qt Version: 4.7.3
Operating System: Linux 2.6.39.3-37-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to scan an image with Skanlite using a Umax Powerlook III scanner

The scanner is detected as umax:/dev/sg6
It is connected to an Adaptec SCSI Connect 2904 PCI card.

If I test the scanner through Yast I get to see the following error:
Test with 'scanimage -d umax:/dev/sg6 -v' failed.
The results are:
scanimage: sane_start: Out of memory
/usr/lib/YaST2/bin/test_scanner_backaend: line 66:   788 Segmentation fault   scanimage -d $SANE_DEVICE -v > /dev/null

The crash can be reproduced every time.

-- Backtrace:
Application: Skanlite (skanlite), signal: Segmentation fault
