I hadn't updated my mythtv packages since last May. I updated yesterday 
using the repository at http://ppa.launchpad.net/mythbuntu/34/ubuntu 
(version updated to above) and when I run mythbackend now I get a 
floating point exception (in gdb):

Is this a known problem? I don't have a mythbackend with symbols 
unfortunately.
