xfce4-panel crash

[Gérald Verdon]

Hello,

    I'm working with xfce 4.0.5, but it seems to me that I already had this problem
before, ie with 4.0.4...

    My xfce4-panel crashed for the third time today. I have this message (because
I ran the panel from a terminal after the first crash):

(xfce4-panel:30006): Gdk-CRITICAL **: file ../../../gdk/x11/gdkselection-x11.c: line 576 
(gdk_text_property_to_utf8_list_for_display): assertion `text != NULL' failed
Segmentation fault

    I have two instances of OpenOffice 1.1.1 working.

    Any idea?

    Thanks,

Gérald
