ok, so once I implemented nsFontEnumeratorQt::GetDefaultFont with a no-op impl,
I got past the unresolved symbol; but now I crash at startup:

(gdb) bt
#0  0x419e273b in QApplication::construct () from /usr/lib/libqt.so.3
#1  0x419e2b65 in QApplication::QApplication () from /usr/lib/libqt.so.3

#5  0x0804ef93 in main (argc=1, argv=0xbfffee94) at

I suppose Qt doesn't like null argc/argv.

The reason this is null is:
#3  0x4173f4e9 in nsAppShellService::Initialize (this=0x8142dc8,
aCmdLineService=0x8142830,
    aNativeAppSupportOrSplashScreen=0x0) at
/home/chb/mozilla/xpfe/appshell/src/nsAppShellService.cpp:166
166       rv = mAppShell->Create(0, nsnull);

My qt version:
qt3-non-mt-3.3.1-41.14
qt3-devel-3.3.1-33
qt3-devel-tools-3.3.1-32
qt3-3.3.1-36.16

Adding new patch to make it compile with current CVS
Thanks, but it won't make too much difference. I had this locally for a while
but I'm just rewritting lots of it so it won't make a difference. 
nsCommonWidget can't be the one receiving the events, the only object which
needs to propagate Qt events is the nsWindow and I'm exporting the dispatcher
there. Also it seems like the drawing widget needs to be different than our
window widget since otherwise we get event storms (e.g. a resize event is
received and Resize is called -> we resize internal widget -> resize signal from
Qt is received -> we dispatch resize event to Mozilla -> Resize is called... ).
Of course until this lands in CVS, and it doesn't look like it will happen
anytime soon, everyone will have to deal with my busy schedule at the moment :(
Some updated. Use with the new GFX patch.
