Anyone seeing anotherfloating point error crashes with mythfrontend in 
svn ? Everything else is fine including myth-setup. What am i doing wrong ?

My config:
Linux Distro: None - built from scratch including mythtv svn
Qt: 3.3.4
Mythtv: SVN
Video Card: Nvidia (however i am starting up frontend thru vnc/ssh/Xnest 
with all giving me the same crash) - i noticed the DisplaySize variable 
in xorg.conf in the newsgroups with people having ati cards, but this 
doesn't seem relevant as mentioned since i am starting mythfrontend 
remotely and my xdpyinfo values are correct.
