Window freezes if opened while the scrollbar handle is being shown

[Leandro Machado]

Binary package hint: compiz

While working with Filezilla today I found a curious bug which I guess lies inside the compiz manager (since it didnt happen in 10.10 with the same Filezilla version). If you open a new window while the scrollbar "handle" (that thing with the two arrows used to move the scrollbar in some apps) is being shown the new window freezes and you have to force close the application.

Steps to reproduce (with Filezilla):
1. Open Filezilla. Go to Edit > Settings;
2. In the settings screen, choose SFTP;
3. Move the mouse cursor over the scrollbar in the bottom of the window (right above the "add keyfile..." button). The scrollbar handle will be shown;
4. While the handle is still on the screen, click on the "add keyfile" button;
5. New window freezes, everybody gets sad ;(

As I said, im reporting this as a Compiz bug since if you do the same steps but wait for the scrollbar handle to disappear before clicking the add keyfile button, everything works flawlessly so Im pretty sure this is not filezilla related.
