This is a nasty problem. My application tends to reload a page over and over. So, after reloading the page five times, a single fired signal would call the Javascript slot function five times, four of which with defunct Javascript contexts. It just so happened that my slot functions sometimes were used to create Flash objects which would crash the application when it was attempted in a bogus Javascript context.

I eventually worked around it by disconnecting all slots from the signals on the application side (you can't do it from the Javascript side because as far as Javascript is concerned the signal has no connection) and reconnecting them during each page load as you normally would.
