Hi,
sorry I can give no coherent reason why it started crashing - to many variables changed the last days.
I upgraded to Centos 7.2, built a tvheadend executable without transcoding by mistake and played with the transcode options (which didn't save with tvh versions of last week). so something went wrong and tvh crashes. Sometimes with backuped older configurations, sometimes in debug builds, sometimes not.
I've locally changes the offending line to check for nullptr and it seems to fix the issue at least in debug builds.

Thanks for having a look,
Thomas
