Have you tried with fvwm? I can partly reproduce the bug with Debian's
default fvwm settings.

1. Log in with fvwm, using Debian's default settings.
2. Open a terminal.
3. Remove the .mozilla directory.
4. Start iceweasel from the terminal.
5. Select File → "Save Page As..." (the Save As dialog should appear
   over the main window).
6. Move the mouse between the main Iceweasel window and the Save As
   dialog (without clicking) back and forth for several dozens of
   seconds (on my machine here, about 40 seconds are needed). This
   has the effect to switch the focus between the two windows.

After several dozens of seconds, a "Warning: Unresponsive script"
dialog appears. This is 100% reproducible.

With Debian's settings, the Save As dialog isn't moved behind
the main window, but anyway, the real cause of the bug is the
"Warning: Unresponsive script" dialog.
