Creating a 4-or-higher tuplet on a 512th or an 8-or-higher tuplet on a 256th crashes Musescore
Steps to reproduce the bug:
1) Create a 512-th note or rest
2) select the 512th and go to Add->Tuplet->Quadruplet (anything with a higher ratio, like quintuplet or sextuplet will also work. Triplets however do work as intended, creating 1024th-triplets.)
3) when trying to split the 512th into the x-tuplet, musescore will crash instead.
Expected behavior: Creation of the appropriate tuplet, or an error message reading that the entered note value is too short (like what happens when trying to tuplet a 1024th)
Actual behavior: Musescore tries to create the tuplet, but crashes.
