[mythtv] June 7th CVS Mythbackend crashes when accessed via mythweb

I updated to CVS yesterday and noticed that anytime I would use mythweb
my backend would segfault. I recompiled and the problem "seemed" to go away
and I could use mythweb without a problem. The backend ran
all night, recorded my scheduled recordings and I had no issues using
mythfrontend to playback a few recordings.
Then this morning I was using mythweb to access it while at work and sure
enough it died again.
Below is a gdb log/backtrace which hopefully will shed some light on what
is causing it.
I'm running this on Slackware 10.1 on An Athlon XP2500+ and myth
was compiled with -march set to pentiumpro.
Up until yesterday I was running 0.18 which was rock solid(compiled
with -march set to athlon). Just in case I tried another compile with
the arch as athlon that crashed as well.
