[mythtv-users] Problems with slave backend after upgrade

After upgrading from .24 to .25 my slave backend does not want to record.

These are the tuners:

video0 - HDPVR
video1 - PVR-250
video2 - PVR-250

Here's what I'm getting in the slave backend logs when I try to pull
up one of the tuners for LiveTV

When LiveTV starts it's using a tuner on the master backend, but when
I change the source the screen goes blank and it eventually segfaults
the frontend on the analog tuners, and gracefully handles the tuner
failure on the HDPVR.

Any ideas what the problem could be?
