[mythtv-users] rpmfusion.org build of mythfrontend requires >2G just to start?

[Brian J. Murrell]

So, I have migrated from Ubuntu to Fedora and installed the mythfrontend
from <http://free.rpmfusion.org/>.

To my shock/surprise/horror I found that trying to start mythfrontend
results in a segfault:

Program terminated with signal 11, Segmentation fault.

It turns out that this is entirely due to my setting a 2GB limit on
process size with ulimit.  If I reset that to unlimited mythfrontend
starts up (well, at least until it crashes the X server but that's a
different issue).

For what possible reason could mythfrontend (libqt I guess) possibly
need more than 2GB just to get started?

But this problem certainly didn't exist in the mythbuntu builds so I
wonder what is different about these rpmfusion builds.

Is there a different repo I should be using for Fedora?

Thoughts?
