Opening a certain score (in MSCZ format) will cause MS3 to crash, although the file was saved with MS3 and can be handled with other programs (Xarchiver, unzip the mscx file and successfully open it with Leafpad etc.). MS3 will close upon opening the score, but will show the preview in the Open Score dialog.
Attached is a /var/log/syslog snippet related to the incident.

What field, "Regression"? This is whether or not something that used to work broke, or didn't work ever since.
I can confirm the crash... even in the latest development build. Stack trace:
