Since I upgraded my system last night, any attempt I make to start a GTK-based
application (firefox, gimp, etc.) while qt-3.3.8b-r2 is also installed has ended in a
segfault.  I am unable to tell which package upgrade was responsible (40 were
upgraded, including some X-related libraries), but whatever changed did so
within the last ~3 weeks.  Tail end of dmesg after a few start attempts:

libqt-mt seems to be the source of the problems, but I'm damned if I know what can
be done about it.  At the moment, I've uninstalled QT3 and am running xfce4, since
KDE3 obviously won't work.  QT4 seems to be okay.

(Note: this is an old system that has been upgraded progressively for ~6 years \
(albeit not always on quite the same hardware) without a reinstall, and there is \
probably some outdated cruft in the configuration.  It never caused a problem before \
today.)
