backtrace of skanlite crash

I get the same symptoms if a state file from a previous launch of skanlite or
skanpage is present:

STEPS TO REPRODUCE (using skanlite as the example, same happens with skanpage)
1. rm -rf ~/.local/share/skanlite
2. skanlite (runs OK)
3. quit skanlite
4. skanlite (Crashes see OBSERVED RESULT)

every time
* The debug output from saned is:
