Problem trying to run MuseScore 2.0.3 AppImage on Ubuntu 15.10
I've followed all the instructions to run the MuseScore 2.0.3 AppImage for Linux (so far without installing it - just trying to run it from the desktop), but unfortunately it closes without warning almost immediately. I see the splash screen (and, for a fraction of a second) the startup window, and then it just disappears - no error message nor anything else.
Just to be clear:
1. I've downloaded the AppImage twice already and am pretty sure it's not corrupted.
2. I've changed the permissions as per instructions.
3. Initially, I had MuseScore 2.0.2 installed, but subsequently uninstalled it. 2.0.3 still won't open.
