Nope ... for now we have only one such report -> yours. But your backtrace shows the threads 1 and 24 fighting against each other.

Kodi is also crashing 2-3 times until all channel data has been loaded if i just restart the vdr server and do nothing within Kodi. I did also try the latest x86 from Milhouse, but same issue (slow loading of challe data and crashing). Tried various builds and can now say that this crashing start happening with builds including the mentioned async process. With the old method everything is working fine.
Any idea what i could test or how i can support to find the reason for this crashing issues?

You did perfectly fine :-) Thx for that. Please open a ticket at trac.kodi.tv an add ksoo as he implemented async epg.

Thx much.
