MusicXML import of tuplets yields elements with zero duration, resulting in corruption/crash

exporting that mscz as xml, importing it, selecting the 1st 3 (tuplet number) and hitting delete, then trying to select the measure leads to a Crash
MuseScore 2.0.2 as well as latest development build, 5a8cf68, Windows 7 (Enterprise, 64bit)

I don't know what tuplets are supposed to look like in MusicXML, so I can't really say for sure if the issue is in the export or the import. But the root cause of the crash is quite apparent: after importing the file, the tuplets themselves (not the notes, but the actual Tuplet objects) all have duration 0/16, where they should have duration 2/16. I'm guessing maybe the export is OK and the import is just failing to set the duration of the tuplet element, but I don't really know.

Problem is in the import. Export is OK. It also reproduces with other MusicXML files containing tuples.

Does not reproduce for me anymore (OS X, commit 421f366 of Nov 1). Please report if this has disappeared or still happens on other platforms.

Still reproduces for me. Try the following:

1) load attached XML file
2) click the "3" on the triplet
3) press "Delete"

Result: the entire triplet is deleted and is not replaced by a rest as it should be, leaving the measure corrupt.

It happens also if the whole tuplet is range-selected (i.e. click on first note and shift+right arrow to select the whole tuplet) and then is cut or deleted.
