Moved the /home/tvheadend/.hts/tvheadend/imagecache/data/ and /home/tvheadend/.hts/tvheadend/imagecache/meta/ directory to a different location, restarted the daemon and was presented with lots of the following messages. Checked the url's but they work.

After letting tvheadend download the new thumbnails for the channels it is clear something is wrong there. All channels have the wrong thumbnail ...

Thought I would add that I'm seeing this as well. Crash log is pretty much identical.

To that end I rebuilt with --disable-imagecache and it hasn't crashed yet (still keeping an eye on it).

Something is definitely wrong here.

More info. This seems to happen exactly every 10 minutes like clockwork. Seriously, my logs show this happening TO THE SECOND. Totally weird.

...and so on every 10 minutes.

Again also, since building from source without imagecache (--disable-imagecache) it hasn't crashed at all.

I had the same issues with channel icon URLs pointing to local files (file:/...), getting the message "httpc: Unknown scheme 'file'" before the CRASH. Somehow the imagecache stuff was changed for the worse...

Can someone report that file:// issue separately, the CURL code was replaced with a custom HTTP client, unfortunately it doesn't therefore support file:// (which is natively handled in CURL) so need to redo that code.

Adam

Ignore that message, file:// is actually handled directly in the imagecache code, plus its not been updated to use the new built-in HTTP client.

Adam

Bugger, had checked out 3.4 to look at something! So imagecache has been updated, however file:// is still trapped within that code, so file:// stuff shouldn't have changed (and it works for me).

Im running into the exact same problem.
I get :

Jun  8 11:40:56 jserver tvheadend[2305]: imagecache: fetch /home/jwkoch/tvheadend/tagesschau24.png
Jun  8 11:40:56 jserver tvheadend[2305]: httpc: Unknown scheme ''

I just dont get why it tries to fetch "/home/jwkoch/tvheadend/tagesschau24.png" as the icon is configured to be at "http://www.lyngsat-logo.com/logo/tv/tt/tagesschau24.png"

Could this be the cause of that?

The crashing started with 14.04 LTS, before I was running 13.10 server on Ubuntu.

The commit b22336f60c784e6b1813994f432797b365aadb17 should fix the crash. Please, report other issues in a separate ticket.
