[mythtv-users] MythTV frontend crashing

[Justin Smith]

Issue #2

Last week I installed Ubuntu 24.04.1 (updated to current) and the latest
MythTV 34 fixes in a newly formatted partition on my Mythbox which is
otherwise running Ubuntu 22.04.5 with the latest MythTV 34 fixes.

While MythTV works fine as expected, I've noticed that the frontend crashes
some time after I've stopped watching a show. I don't notice the crash
because I've either switched off the TV or watching some other TV app. Note
that it's a relatively minor annoyance because it has never happened during
a show. The frontend never crashed under Ubuntu 22.04.

Here is a typical snippet from the frontend log:

Then the crash... There's nothing seemly unusual in the backed log at this
time:

sock(556fd1fb22c0) 'zebola' disconnected

Any ideas on how to fix this?

Thanks,
Justin.
