Subject: More hints on that long-lasting QIconView crash
X-MARC-Message: https://marc.info/?l=kde-core-devel&m=95186949818375

As most of you know, alas, konqueror has a very nasty bug,
making it crash sometimes when clicking on a file (like a text file)
that opens a new view, because somehow something happens in
the already-deleted icon view.

I tracked it down, finally !

On a mouseReleaseEvent, QIconView does:

        emit mouseButtonClicked( e->button(), item, e->globalPos() );
        emit clicked( item );
        emit clicked( item, e->globalPos() );  

Since the first one (or the second, didn't check) deletes
the iconview (in konqueror, which switches to another view),
when it comes back here, the third emit
looks into a deleted list of receivers, hence the crash...

No idea what a possible fix could be, though... (or it would be hacky,
like relying on the order those emits are done).

Reggie ?

Is it wrong for konqueror to connect to more than one of those signals ?
