Assertion failure on trying to insert Figured Bass in debug build of MuseScore
Steps to reproduce:
1. Create a new score.
2. Put a note to the score.
3. Select a note.
4. Press Ctrl+G.
This bug prevented me from testing another bug report so it should probably be checked too after this one is fixed.
