Unable to install

Dear all,

I have CentOS 6U4, and Java :

# rpm -qa|grep jre

jre-1.7.0_25-fcs.x86_64

I am root user, so no lack of privileges.

When I try to install Aris Express :

# javaws express.jnlp



(<unknown>:17256): Gtk-CRITICAL **: IA__gtk_message_dialog_set_markup: assertion `GTK_IS_MESSAGE_DIALOG (message_dialog)' failed

Segmentation fault (core dumped)

Help.
