I can't imagine if I "produced" this by using it in a special way, but I clicked around the web ui. This happend on a Ubuntu 14.04 (LTS) machine with rel. newly upgraded TvHeadend 4.0.4 (from repository), upgraded from 3.4. This happened never before as I can remember.

I you need some special informations, please contact me.

Thanks.

I don't think this is a bug caused by Tvheadend but a dodgy driver, I got the same divide error on my system at some point (it was caused by the ts2020 driver) upgrading to the latest media_tree fixed the issue (I now run the longterm kernel (3.18) and haven't had any issues in a long time).

However I could be totally wrong in your case & it might be something completely different (I'm no expert, you'll have to wait for one to reply ).

Sure, this could be. But I'm no expert in this, too. And the stacktrace doesn't point in a clear direction for me, except the word "tvheadend" :-) We'll see...

Status changed from New to Rejected

Yes, upgrade the driver (kernel) and if it does not not help, report this issue to the driver author.
