Description

I'm not sure, but it seems plugin's bug.
Tuning to the some channels on 4.8E satellite segfault occures:
[Wed Apr 30 21:49:33 2014] receiver on dev[11446]: segfault at 0 ip b737fc3c sp 95f55ef0 error 6 in libc-2.17.so[b72fd000+185000]
For example one of those channels is (FTA):
1st Baltic Music channel:11843:hC34M2S0:S4.8E:27500:6231=2:6232=@3:0:0:6230:85:13:0
I have saved .ts for this channel with plugin detatched:
http://www.filefactory.com/file/3852a8qi4z11/1st_Baltic_Music_channel.tgz
Replaying this file cause segfault as well.

My backtrace:
Program received signal SIGSEGV, Segmentation fault.
