[mythtv-users] Latest Mythbuntu build (0.27.0+fixes.20131010 .e59e5f6) backend segfaults

[Andre Newman]

I just had to remove the latest Mythbuntu build from today and re-install the previous build from my /var/cache/apt/archive/

I removed: 
mythtv-backend 2:0.27.0+fixes.20131010.e59e5f6-0ubuntu0mythbuntu2

And replaced with:

mythtv-backend 2:0.27.0+fixes.20131008.756d95d-0ubuntu0mythbuntu2

Also:

mythtv-backend-master 2:0.27.0+fixes.20131010.e59e5f6-0ubuntu0mythbuntu2

Replaced with:

mythtv-backend-master 2:0.27.0+fixes.20131008.756d95d-0ubuntu0mythbuntu2

mythbackend was segfaulting after a few minutes from service startup, regularly and repeatably. Start a test recording, wait a few seconds, click recorded programs in MythWeb and wait for the segfault.
