Without Flip4Mac installed, this ASSERT is hit at <http://broadband.tsn.ca/> after the sheet that lets you know you don't have the plugin installed pops up. Not reproducible with Flip4Mac installed or in a release build. See also bug 14899 and bug 14339.

Like bug 14899, !d->m_view->needsLayout() is causing this to fail.

Comment 2 2007-10-23 10:46:07 PDT
This bug belongs to the general "letting arbitrary stuff happen under attach()" category. In this case, the plugin that was just created puts up a sheet which changes the window's key status and triggers a redisplay.

Comment on attachment 16825 [details] Defer updateWidget() until after attach() This patch caused test regressions. I think waiting until after layout was a mistake. The updating should happen sooner.
