When i close xulrunner applications (I tested only icedove / iceweasel, but i
guess it's a xulrunner problem) program windows close but the processes remain
active and eats 100% cpu time.
This behaviour occurs on different profiles / different PCs (tested on a
desktop and a laptop, both 64bit unstable, 1 AMD based, 1 Intel based).
This occurs even on a empty profile (or in safe mode) just opening the default
page (about:home).
Apparently this don't cause any dataloss or any error in profile data, but it's
quite annoying as it makes opening new browser session impossibile.
How can i debug this situation further and provide more info?
