[mythtv-users] Segfault while tuning channel in mythtv 31.0

Hi all,

I just upgraded from mythtv 30.0 to 31.0 (fixes) on Gentoo and now I get
a segfault when it is tuning a channel.

Happens when EIT scan starts or when I start Live TV. Did not test
recording yet.

Output in gdb for Live TV:

Thread 8 "TVRecEvent" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fe57b7fe700 (LWP 30677)]
0x00007fe5a4651a6c in ?? () from /usr/lib64/libmythtv-31.so.31

Attaching full gdb.txt.

After upgrading, I went into mythtv-setup and noticed that the
"DVBInput" is configured as capture cards delivery system, which is not
an option in the select box. So, I changed that to "DVB-S2". But that
did not change anything regarding the crash.

Any hints would be greatly appreciated.

Regards,
Thomas
