I had experienced a problem after squashing migrations. The problem is described here: http://stackoverflow.com/questions/31606372/django-migrations-build-graph-has-a-bug
I have not a description of how to reproduce the bug, but I think I can say why the source code is wrong (see the link). Do you think this is enough to open a bug report?
