 When I attempt to choose "Edit Recording Schedule" from the context menu
 for any recording, MythTV segfaults immediately and dumps me to desktop.
 Running with the "-v all" option, no message is displayed from the time of
 the keypress to the dump to desktop.  Sometimes, but not always, it says
 segmentation fault - otherwise the behavior is identical and virtually
 instant.  The same occurs if I try to access it through manage recordings.
 Scheduling a new recording has the exact same effect, either using the
 guide or program finder.

 The error replicates 100% of the time on both the front and backend
 machines.  Frontend is AMD Sempron 140 w/ HVR-1800 DVB card and Geforce
 8200 on board.  Backend is AMD Phenom II 3.2 X4 w/ HVR-1800 DVB and
 PVR-500 analog cards and GT240 video card.  (Other machines in the house
 replicate the error as well).

 I have checked the database and repaired/optimized.  No signs of errors.
 I have tried all the available themes without effect.  It began after
 upgrade to 0.24.  I'm running Gentoo Linux 64 bit and kernel 2.6.34.
 Building out of the official MythTV Gentoo repository, most recent stable
 version. (In Gentoo, that's 0.24_p20110201.)  Compile options are plain
 vanilla -fomit-frame-poiner -O2.  Compiler is GCC 4.4.4.

 Rebuilt with +debug useflag to get a trace.  When run with GDB, it still
 does not work, but instead freezes up and no longer accepts input at all
 at the same place (no immediate dump to desktop).

 It appears to be a segmentation fault in MythUI-0.24.so.0

 Program received signal SIGSEGV, Segmentation fault.
 0x00007ffff51f3228 in MythScreenType::SetFocusWidget(MythUIType*) () from
 /usr/lib/libmythui-0.24.so.0

 I have attached the complete GDB output.  Please let me know if anything
 else would helpful, and thank you in advance for your assistance.
