Minor 1. Open any *.ugenedb file with assembly or import any BAM/SAM file.
2. If view is opened, close it.
Expected state: assembly document is in the project, there are no views.
3. Delete (or rename) source *.ugenedb file.
4. Open a new view for assembly document.
Current state: UGENE crashes.
There is a regular checks for file changes for all formats, except *.ugenedb (see ProjectViewImpl.cpp, DocumentUpdater::update()). It is need to do anything with missing *.ugenedb file.
