Nope, that's not the problem. It is definitely a DVB EIT issue, as if I disable this feature with configure, the segfault goes away (interestingly, if I simply disable scanning on all sources, it has no effect).

I can only replicate it if I have recordings scheduled on the DVB tuners when I start up mythbackend. Which happenned to be the only situation that was occurring, before I retested it this morning.

As another, possibly relevant datapoint, I'm in Australia, so we don't have real OTA guides, merely current, and next.

Still there with r9116. Will try to identify the problematic commit tonight.

Please try the latest SVN.

If it works close the ticket, if it doesn't work, apply nit-debug.3.patch and attach the output.
