Crash when running transpose with title selected

1. Open attached score
2. click the title
3. Notes->Transpose
4. select something other than unison in the tranpose by interval dropdown
5. OK

Result: crash
Expected result: At step 3, MuseScore probably should have put up the dialog saying nothing was selected and asking if I want to transpose the whole score.

I ran into this when trying to transpose a score, not realizing a title was selected. I *was* wondering, though, why the option to transpose by key in the transpose dialog was greyed out.
