All my fe's are on F7. None of the Myth apps segfault. I don't know where you 
heard what you heard, but you did not hear it from me.

I never said the fe was segfaulting, and it does not. KDE does not care if an 
app was stopped by a SIGINT, SIGTERM, SIGSEGV, ...

The KDE autologin function does not figure into it. I explicitly said I 
started the fe after login by clicking an icon.

I agree with you, that the observed behavior has nothing to do with myth.
That is why I mentioned that it's happening on the proprietary nvidia driver.
None of my other fe's has that problem. I have had similar experiences with 
the nvidia drivers before.

Cheers,
Remco
