[Bug 953442] Re: mythfrontend.real crashed with SIGSEGV in QCoreApplication::postEvent()
*** This bug is a duplicate of bug 962981 ***
https://bugs.launchpad.net/bugs/962981
If I recall correctly, this would be a first time run I executed on my
notebook, and MythTV come up with the initial configuration screen
(pick-a-flag) since it failed to connect to the backend with the
existing password from a previous install, imported into the home
directory.
I entered the new IP and password provided by the backend. It starts
trying to connect to the backend. Crash. I can't say if it crashed
immediately after I pressed enter or shortly therafter.
I've been having problems with the frontend more recently as well when
subsequent attempts to connect after the (blocked) first connect fail
and crash and I can't kill the processes, could be related.
