[mythtv] Reproducable crash mythfrontend (recent SVN version)

[Niels den Otter]

Mythtv-Dev,

I observe frequent crashes of mythfrontend. My current Mythtv version is SVN
Revision: 6857 (Last Changed Date: 2005-07-18 22:07:44 +0200). I believe I can
reproduce at least one of the type of crashes and that is when Commercial
Flagging starts. Here is some output during one of these crashes:

------------------------------------------------------------------

After this if I try to use Live-TV on the frontend all inputs are reported
busy. So no live-TV. Restarting the backend helps in these cases.

Please let me know if more information or debugging is needed.
