With Qt 4.5 tp1, Qt apps, including the sample web browser from the qtdemo, will crash if some plugins are present. I have noticed this with the Move Networks plugin (http://www.movenetworks.com/) and the Microsoft Silverlight plugin.
I have confirmed this on Mac OS X 10.4.11 and Mac OS X 10.5.4. Here is a backtrace: Program received signal EXC_BAD_ACCESS, Could not access memory.
