LMS troubled by files outside of scan folder

Upgraded my LMS from 7.7.2 to 7.9 the other week. Since installation the server crashes every day. Everytime after image scaling complaints in the server log looking like this:

2069: *** glibc detected *** /opt/ssods4/bin/perl: free(): invalid next size (normal): 0x056bb990 ***

I can see why LMS is having trouble handling these pics since they're quite huge. What's bothering me though is that they aren't in my scan folder! I haven't scanned anything else but my music folder at /share/Multimedia/Music. QNAP path that is. Maybe it's NAS related but maybe some LMS savvy guy in general has a clue.

How does LMS pick up those paths?
