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.
