I have been debugging exactly the same situation in the Activities KIO
Slave. I tried putting the affected parts in their own thread, and
that didn't work. Right now I have a processEvents() call before using
those objects which at least changes some values (it used to stay
stuck with the information it got when it was first initialized) but
those are stale.

The implementation that went into 4.10 depends on no signal/slots and
that works, but it is of course less efficient. I've given up for the
moment in trying to find a solution, but if you manage to solve your
situation please let me know.
