Ok, I've got a fix for it:

------------------------------------------------------------
Basically, what was happening was that when building a list of windows
to be raised, it would include icon_pixmap_w, which was a NULL (since
the window had no icon).
The list of windows to be raised was passed to the X server in the
XRestackWindows(dpy,wins,i);
call. In this call, X was taking the NULL in wins to mean the end of
the list, rather than relying on i. Since the main window is in wins[]
after the NULL, it never got re-stacked.
