Mozilla firefox over ssh: Gdk-ERROR **: BadDrawable/BadAccess

Thu Apr 22 08:56:00 GMT 2004

In a cygwin xterm window, I ssh to a Linux machine and try to run 
firefox.

; ssh -X emmaline.algorithmica.se
Last login: Thu Apr 22 09:54:47 2004 from merapi.algorithmica.se
; echo $DISPLAY
localhost:12.0
; firefox

Gdk-CRITICAL **: file gdkimage.c: line 416 (gdk_image_destroy): assertion `image != NULL' failed.

Gdk-CRITICAL **: file gdkimage.c: line 416 (gdk_image_destroy): assertion `image != NULL' failed.

; 

This worked before I upgraded (actually reinstalled due failed upgrade)
cygwin a few days ago. Xterm, emacs and Netscape 4.8 still work.

Any ideas?
