I'm running up-to-date Mythbuntu 9.04, using JYA's trunk repository.   
Latest nvidia 190 series drivers (190.42? -- it was a little worse  
with the 185.36 series drivers), again from JYA's repository.

A rebuild with compile-type=profile and DEB_BUILD_OPTIONS=nostrip will  
get the symbols.  I had forgotten that I wasn't rolling my own builds  
anymore.

I'm beginning to wonder whether its a memory leak issue.  I notice  
that with the fanart, etc. mythfrontend grows to over 600MB resident  
quite quickly.  I'm running on a 2GB ion with no swap -- so it could  
be related to that.  Though I always die exiting the PBB or a  
recording and the dump is in a destructor -- which should be releasing  
memory.

David.
