[mythtvnz] segfault after upgrade

[Ross and Jemima Knudsen]

Hi all,

Well I finally decided to give 0.22 a go.  I upgraded it last night but 
am now having problems with the backend.  I have tried reinstalling 
those packages a couple of times but with no luck.  I'm using JYA's 
release repo on Ubuntu 9.04 AMD64.  Starting the frontend results in it 
complaining that the backend is not available and to check my IP 
addresses etc.  Sure enough the backend process is not running and 
manually forcing it to restart results in a segfault:

mythserver kernel: [ 1410.241167] mythbackend[7123]: segfault at 
7fff98da1e18 ip 00007f2189fcdb37 sp 00007fff98da1e00 error 6 in 
libQtCore.so.4.5.0[7f2189f14000+240000]

Looks to be some error with libQtCore, and its probably something 
straight forward but what have I missed?

Regards
Rossco
