Subsonic crashing

[DanielMalmgren]

Hi.
I've used Subsonic for many years without many problems, but lately it has started crashing. Just out of the blue in the middle of the night when nobody is using it. I'm not 100%, but I think this is since upgrading to 4.9beta4 or maybe 4.9beta3. I get nothing about the crash in subsonic.log, but in subsonic_sh.log it says that a fatal error has been detected and it references another log in /usr/share/subsonic. I'm attaching that log, hope it'll say somebody something about what's happening. Looks like the log contains all relevant info about my system as well.
