Description
I wanted to have a clean channel list, so I deleted all muxes, what worked without a problem.
Then I added one mux by "Add DVB Network by location" and enabled "autodetect muxes". After enabling
this option tvheadend crashed. If I start tvheadend again ist crashes each time:

I'll try and replicate this, but do you have the configuration that was causing this crash? That could be useful to help replicate the failure.

Updated by Damn, no I deleted the config, sorry.
If it helps: it was rather a very old config, created with v2.9, I think.
I'll try to repeat the steps.

I tried the same steps again (sadly without gdb 
), with a clean config and it crashed, but after a restart everything was ok again.
Next try with with another clean config resulted in no crashes.
The only thing I noticed are these lines in debug output:

Maybe tvheadend crashes under some circumstances, if there are unreferenced objects?

Rene,
are you still seeing this? I've never had a chance to try replicating it.

honestly I did not try again, I'd say you can close the ticket. If it will happen again, I'll add the information here.
