[mythtv-users] Generating preview of running recording breaks it

Sun Mar 5 21:19:54 UTC 2006

Version: 0.19

Generating a preview (by pressing "recorded programs" in Mythweb)
of a running recording breaks the recording  into two parts:
One before the preview and one after.

Looking inthe log it seems like the backend crashes.
Attaching a gdb log created by gdb:ing the core dump.
Seems to be thread 1 that crashes
