FWIW, in master at least, the problem seems to have something to do with a nested tuplet, where the inner tuplet has a bad value for its parent.
This problem is related to another: if you save the imported midifile as .mscz (I mean right before crashing), the saved file is corrupted. Even when you don't change any import option. Try it yourself with the attached sockhop midifile.
Problem 1: import it in MuseScore (any version) then save as .mscz, then close the file and open the .mscz file ==> Result: file corrupted
Problem 2: import again, turn the swing option on and play the song ==> MuseScore crashes after a few seconds
These problems occur with many midifiles.
