Only happens sometimes (roughly 50% of the time?)
I've been unable to trigger this when quitting a chart midway through, it must be at the end
Not sure the log file will be helpful, since the last line says "Exiting song" with no exception or error close to it.
This may be some kind bug specific to my system, since this exact issue (repeated crashes before score screen) has happened to me in the past (same linux distro on different hard drive) when playing a completely different rhythm game (clone hero)
