Backend crashes on 0.21-fixes SVN 16578

Reported by: mb@… Owned by: Anduin Withers
Priority: major Milestone: 0.21.1
Component: mythtv Version: 0.21-fixes
Severity: medium Keywords: segfault backend
Cc: Ticket locked: no

Description

I am getting segmentation faults on a regular basis with the 0.21-fixes branch on my gentoo based mythtv (made my own overlay) older svn-versions of 0.21-fixes had the same problem so I "upgraded" on my own and made a debug version. When crashed with gdb attached I am getting the attached backtrace.

If I need to give you further information, please tell me.

The attached patch should fix it. In the future, backtraces should be generated following the steps here (roughly): http://www.mythtv.org/docs/mythtv-HOWTO-22.html#ss22.2 . While it is usually obvious which thread caused the SIGSEGV, having the thread id makes the initial search faster.

Thank you. It fixes the bug. When does this patch make it into 0.21-fixes?
