You need to install tvheadend-dbg along with the main deb, it may also help if you install corekeeper, gdb & change TVH_ARGS="" to TVH_ARGS="-D" in /etc/default/tvheadend (you'll need to stop & start the daemon for the changes to take effect). So that when tvheadend does crash you'll be given a core dump to run a gdb trace on [usually dropped in /var/crash/<uid> if you have corekeeper installed].
A simple gdb trace would be
sudo gdb /usr/bin/tvheadend /path/to/core.file gdb> set logging on /home/hts/debug.log gdb> bt full
!* gdb> means enter into gdb.
Then upload the log here.

I have run those commands. When i run bt full i get the response "No stack" and the logfile only contains "No stack".
Do i need to wait for it to crash?

Never mind just read the rest of the post :)
Args added, tvheadend-dbg installed and service restarted.

Yes, you need to wait for it to crash so corekeeper can catch the dump, you won't get anything without the dump [You won't even get a dump if you're not running tvheadend without the -D switch].
Edit: I saw your post just as I wrote the above.

TVHeadend crashed again at 11:20 but the debug log was empty. rant he commands you gave and still only got "No Stack".
Do i have to change the /path/to/core.file to something, if so what too?
sudo gdb /usr/bin/tvheadend /path/to/core.file

You need to change that to the core files location.
Type
ls /var/crash
That command should list a directory, usually a number [User ID] & in that directory should be the coredump.
For example. /var/crash/106/<random numbers>-tvheadend-core.
So you would run.
sudo gdb /usr/bin/tvheadend /var/crash/106/12354567890-tvheadend-core
Your coredump will be named something totally different, you may even have more than one [you can find the newest dump by doing ls /var/crash/<uid> -l and checking the date].

In /var/crash I only have files, one of them is _usr_bin_tvheadend.118.crash
but when I run sudo gdb /usr/bin/tvheadend /var/crash/_usr_bin_tvheadend.118.crash
it says not a core dump: file format not recognised
the hts user is uid 118 though
Opening the file in a text editor shows its got lots of stuff in there. I can send you the file if you want (it's 22MB though)

Will that be in the apt repository in the morning? if so I'll install it first thing.

- Status changed from New to Fixed
Closing. Open a new bug with the backtrace, if you hit another one.
