[Qt-interest] Full screen QtWebKit Flash application -> SEGFAULT

[Brian]

Using a Flash application that supports full screen (specifically Vimeo.com)
causes a WebKit level crash, although it's not clear to me that it's
WebKit's fault. Seems more likely the fault is with Qt, or even our
application? Backtrace follows.

Thanks,
Brina
