Crash Bringing Up Page Settings Dialog
Be editing a music file.
Bring up Tools / Page Setup.
Result: Musescore frequently (about 30% of the time?) freezes, and you have to eventually kill it and recover work. The recovery isn't always complete, so I may have to redo some work each time.
This has happened over 10 times to me today alone, and probably 100 so far. These random crashes (there are other triggers as well, such as deleting a staff), cause me to lose a lot of productivity.
The included file (which was originally imported from MusicXML because that was the only way to save it after Tools Unroll, per the previously reported bug.
However, this crash is not specific to any music file. It was happened when editing every single one of my music files. Getting a new computer did not cause this or other frequent musescore bugs to go away.
