ALT Linux Bugzilla – #29511

Created attachment 5977 [details]
Fix from upstream

Reproducible: Always

Steps to Reproduce:
1.Update to latest version from Sisyphus
2.Start the daemon
3.wait a couple of seconds for segfault (or if no DB, go to the web interface and add some files, then wait for segfault)
Actual Results:  
Segfault with the following in syslog:

kernel: mediatomb[10301]: segfault at 25 ip b724bab7 sp b12d0af0 error 4 in libavformat.so.53.32.100[b71a1000+d3000]

It seems that initializing the pointer does the trick:
