Qt Creator crashes when updating ui file externally

Hi guys,
I know you wouldn't like to hear that but I don't have a reproducible test case for you. All I can provide is a description of my environment and a stacktrace.

So here's what I do. I have a project in git, which has some ui files. At one point I had my ui file opened in text mode (where XML is shown) and I did git checkout – myfile.ui. When I pressed yes on 'do you want to reload..?' pop-up Qt Creator crashed.

And here's the stacktrace.

Sorry for not giving you the reproducible sample. I hope you could trace the issue.

Cheers,
