[mythtv-users] mythfrontend __dynamic_cast segfault

When I select "Watch Recordings" mythfrontend segfaults. This might be
an interaction with my version of libstdc++ -- 3.3.4. A backtrace
follows. mythtv 0.15 worked fine for me. I'm using mythtv 0.16 now and
am experiencing these __dynamic_cast segfaults in many places. I'd
greatly appreciate any help!

Please cc me in your reply. Cheers,

mythtv 0.16
Qt 3.3.3
