"Binary package hint: gnome-panel

Steps to reproduce:
Turn compiz on
Drag a window from the window list(how do you call it, normally at the bottom
of your screen) to another side of the cube(with a empty desktop).
You have successfully reproduced it :)

I don't now why i drag a window(button) to another side of the cube, but
gnome-panel crashes ;)

I've opened a bug on cairo: https://bugs.freedesktop.org/show_bug.cgi?id=10359
libwnck should probably not call cairo_rectangle with a cr=0x0 though
Comment 1 Vincent Untz 2007-04-29 17:43:46 UTC 
The question is how do we have drawable == NULL in draw_window(). It means gdk_pixmap_new() returns NULL in wnck_update_drag_icon().

This means one of these is failing:

  g_return_val_if_fail (drawable == NULL || GDK_IS_DRAWABLE (drawable), NULL);
  g_return_val_if_fail ((drawable != NULL) || (depth != -1), NULL);
  g_return_val_if_fail ((width != 0) && (height != 0), NULL);
  if (GDK_IS_WINDOW (drawable) && GDK_WINDOW_DESTROYED (drawable))

drawable in gdk_pixmap_new() is widget->window where widget is the pager. I can't see how it could be NULL or an invalid drawable or destroyed while someone is doing a drag and drop.
width and height are not null according to the stack trace.

So I'm lost.

I'd love to know if it's easily reproducable, and if it happens only with compiz (could explain why I can't reproduce...).
