[mythtv-users] Backtrace when running mythtv-setup over X

Mon May 7 11:23:48 UTC 2012

Hi

I'm using mythtv 0.24-fixes.

When I try and run mythtv-setup remotely (via ssh -X), it fails to
execute. Upon further investigation it seems that mythtv-setup.real
crashes with a memory corruption error and produces the following backtrace.

This is perfectly repeatable. I don't mistrust the hardware as
everything else is running just fine. I can also run mythtv-setup
without problems locally on the backend rather than via X.

Any idea what might be wrong? Any further info I can provide?

Thanks, Jan
