Crash if user drops symbol from Master palette onto a lyric syllable
1) Open a musescore written song
2) open master palette
3) click on a note on the score (in my case I clicked on the F note on the first lyric line
" Xin cho con biet" (the note a the word biet)
4) select symbol, scroll down about 1/3 and choose the black note with stem down
5) pull the symbol and line up on the note and it crashed.
Note that if I use a diamond symbol and it worked ok
