before i left for vacation, i confirmed with Thiago that the event loop 
nestedness count is indeed screwing up. we don't know why, but the count is 
indeed wrong and that is why the deleteLater()s are never working.

it seems to have something to do with x11EventFilter, as all the backtrackes 
go through there when the count is incorrect.

so we have a couple of options:

* try to figure out why x11EventFilter is wreaking havoc on the count

* implement that unfortunate QTimer::singleShot(0) work-around along with a 
comment explaining why it is there

i'm fine with either, mostly because i have time for neither at the moment :/
