Mozilla crashes with obscure messages

Hallo,

I don't know if I am in the right place, if not please tell me where I should ask for help.

I use Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529.
I connect with an X-Terminal on a RedHat6.3-Server and sometimes
(aprox. 10 times a day) following messages on console (after that Mozilla crashes):

Gtk-CRITICAL **: file gtkdnd.c: line 623 (gtk_drag_get_data): assertion `widget != NULL' failed.
Xlib:  extension "RENDER" missing on display "slbxgm:0.0".
Gdk-ERROR **: BadAlloc (insufficient resources for operation)

Gdk-ERROR **: BadDrawable (invalid Pixmap or Window parameter)
   serial 21687 error_code 9 request_code 66 minor_code 0
status is failure
Gdk-ERROR **: BadAlloc (insufficient resources for operation)
   serial 1152177 error_code 11 request_code 53 minor_code 0
Gdk-ERROR **: BadDrawable (invalid Pixmap or Window parameter)
   serial 1152226 error_code 9 request_code 66 minor_code 0

Please notice that only one of these errors causes a crash. The above list comes from several sessions.

Thank you,
Andreas
