Crash when creating tuplets on multiple chords/rests

When I mark the last three eighth rests and press CTRL+3 to make them triples, I get a crash. The same happens when I enter three notes first, select them and do the grouping on them.
I don't know if that's related, but when I do the triplets on only one rest, I get the triplet grouping, but entering the second note in the group, I get very weird note values instead of the one I'd expect.
