[Bug 1000771] Re: mythfrontend.real crashed with SIGSEGV in pthread_join()

 

Mario, it looks like 
https://github.com/Pulse-Eight/libcec/commit/5806561ef938c6201adf4dccb3f80cebb1aa215b

fixes the issue, but the packaged version of libcec / libcec-dev is
earlier than that.

This is affecting MythTV trunk and can cause segfaults, including in
mythtv-setup.
