He had foo.h: Q_OBJECT
and foo.cpp: Q_OBJECT
and foo.cpp was including foo.moc, but not moc_foo.moc.
So the moc file for the qobject in foo.cpp wasn't getting created.
I used kdelibs/kdeui/fonts/kfontcombobox.cpp as example to find out
he needed moc_foo.moc as well.

Sounds like a bug in automoc, actually, if it's not handling this case...
