Mythfrontend fails with segfault after system upgrade

After doing some upgrades my mythfrontend fails to start with a
segmentation fault.

What I've done in particular is to update 10.1-Stable (from one compiled in
mid-december), and upgraded the nvidia-driver from 331.67 to the current
340.65.
When I noticed the error I tried to downgrade both the system and driver to
the previous state, but oddly mythfrontend kept failing the same way.

As I'm not much of a programmer myself I hope someone can make sense of the
log below. I'm grateful for any hints or tips that might help in resolving
this.
