Any file inside storage directory besides bluecherry created directories / files cause crash

[curtishall]

Reproduce:

Place any regular text files (I did three) in /var/lib/bluecherry/recordings:

-rw-r--r-- 1 root             root                5 Jan 16 00:08 test1
-rw-r--r-- 1 root             root               42 Jan 16 00:08 test2
-rw-r--r-- 1 root             root               42 Jan 16 00:08 test3

Upon restart the server will crash after "Checking location: /var/lib/bluecherry/recordings":
