Crash when dragging a window to top of main window

[GoogleCodeExporter]

Just drag a window to the top left corner and it will crash.

Version: r784

Gdb output(moving the finance window):

Program received signal SIGSEGV, Segmentation fault.

Looks like it's not only when moving to the top left corner, but always when 
the y coordinate of the text in the titlebar is < 0.
