Couple of crashes with Creator 2.1 beta

[Guest]

Running into some random crashes with 2.1 beta. Especially when I have multiple projects open and when I close project from Project View. Anybody facing this? I'm on WinXP. But doesn't happen always

I use QtCreator from gitorious, but had crashes only with Qml designer.

Can you get a backtrace and file a bug report? Thanks!
