The "exclusiveness" could be the problem; i.e. the other one gets unchecked,
which might call activate? In KWord (kwview.cc, e.g. KWView::viewPageMode)
we check if ( action->isChecked() ) from the slot. But that's also because when
switching between viewmodes always one viewmode has to be checked, which
isn't the case for you. Hmm, but we do have subscript/superscript actions too,
and exclusive too, and I haven't seen the bug you talk about there.
Anyway, backtraces will certainly tell you what's happening.
