SUMMARY
Skanlite crashes (segfaults) after start, when no Scanner is connected
STEPS TO REPRODUCE
1. ensure no scanner is connected
2. start Skanlite (from command line without arguments)
3. When a window opens ("Looking for devices. Please wait.") just wait some
seconds until the crash happens
OBSERVED RESULT
Skanlite crashes.
EXPECTED RESULT
Show empty list of Scanners (possibly together with an additional message to
connect a scanner)

ADDITIONAL INFORMATION
When the scanner is connected, the built-in Webcam of the Laptop is shown in
the list of scanners as well as the scanner. The Webcam is selected by default
then. It can be used, so Skanlite would read a still image from the Webcam.
When selecting the Scanner, it works well.
