Reproducible: Always

Steps to Reproduce:
1. Start guvciew (either using the menu or the terminal)

3. The program crashes with a segmentation fault.
Actual Results:

I tried the more recent versions in tree and the bug is reproducible with the following versions: 1.6.1, 1.7.1, 1.7.2. I do not know if the bug is reproducible with version 1.7.3, because it crashes with a segmentation fault much earlier.

[Comment 5 Pacho Ramos 2016-03-01 17:50:55 UTC]

please retry with 2.0.3
