The commands:
- baloosearch --type video test
- baloosearch --type audio test
result in a crash (SIGSEGV) but the commands:
- baloosearch --type text test
- baloosearch --type document test
- baloosearch test
work as expected.



The crash backtrace taken with gdb:
(gdb) run --type audio test
<SNIP>
Program received signal SIGSEGV, Segmentation fault.
