gnome-mag-0.10.2 error messages

[Sandie Vanderme <sandie vanderme bull net>]

Hello,

I've compiled gnome-2.2.1 with gnome-mag-0.10.2.
I've tested the magnifier and it seems to work correctly.
The problem is that there are some critical error messages at startup.
The messages are the following :
(magnifier:17764): Gdk-CRITICAL **: file gdkdraw.c: line 759: assertion
`GDK_IS_DRAWABLE (drawable)' failed

HOTSPOT  0 0
getting cursor 20388a78, mask 20388b18
.
.
deltas too big to scroll

(magnifier:17764): GLib-GObject-CRITICAL **: file gobject.c: line 1337:
assertion `G_IS_OBJECT (object)' failed

Is it a known bug in gnome-mag-0.10.2 or is gnome badly compiled or
installed on my machine ?

Thanks for an answer.

Sandie.
