[mythtv] SVN mythtv-setup on PowerPC Segmentation fault

[Eric Pheatt]

I'm getting a Segmentation fault when I try and run mythtv-setup from
current SVN on my KuroHG running debian.

The KuroHG is a PowerPC without AltiVec, so I had to patch
libs/libmythmpeg2/cpu_state.c at line 43 and 120 to #ifdef
HAVE_ALTIVEC from #ifdef ARCH_PPC to complete the compile with
--disable-altivec passed to configure.

I've never used gdb before but following the instructions from the
docs produced the following.

[Thread debugging using libthread_db enabled]
[New Thread 805491520 (LWP 2681)]
Qt: gdb: -nograb added to command-line options.
         Use the -dograb option to enforce grabbing.

I'm stumped as to the next steps since others on the kurobox.com
forums have been able to get mythtv working on Gentoo and debian.

Thanks,
