I am running a recent built of Kodi 18 alpha on ubuntu 16.04.

A PulseEight USB-CEC connects my PC with my Panasonic sound base (which connects to my Philips TV). My system usually goes to sleep after 15 minutes of idle time or by pressing the power-button on my remote. Via CEC my sound base and TV are also set to sleep.

When resuming from standby, either for a scheuled recording or after a manual switch on with my remote, kodi frequently crashes and restarts. This happens so fast, that I hardly notice before my tv screen is turned on.  After the restart I sometimes get an CEC intialization error popping up but afer a few seconds CEC works fine as does kodi.

I built kodi, vdr and libcec from their sources on github.

When I run through the many crashlogs, most of them show the same segmentation fault due to a problem with libcec.so.4:

Program terminated with signal SIGSEGV, Segmentation fault.

I found the following issue report: https://github.com/Pulse-Eight/libcec/issues/296 which sounds somewhat similar to what I am experiencing.

Is this still applicable to kodi 18?
if this is related to my issue, would this need fixing in libcec or kodi code?
What more can I do to help troubleshoot the issue?

I can't imagine I am the only having this issue ... Are there really so few kodi 18 alpha on Ubuntu users with Pulse-Eight USB-CEC adapters?
If others with a similar setup don't see this issue, it must be in my configuration. Will try to reproduce with a clean install, as soon as family gives thump up.
