Image Editor from Charters in MyCollection

Created by: StephanMa

Image Tool crashes when Image Editor is opened from a published "MyCollection"-Charter.

1. Create a private Collection
2. Add bookmarked Charters to it and publish it
3. Go to Fonds and open the Charter from the self-created Collection
4. Open the Charter and try to Enter the Image Editor

Error was verified by Bernhard as well...

Issue concerning @image-tools.widget.xml will be fixed together with Issue #245 (closed)
