Dear All I just updated the cvs and built the gretl under my Ubuntu 10.04. However, gretl crashes when I click in the mainmenu "Tools->Preferences->General." I got an message as follows: (gretl_x11:15034): Gtk-CRITICAL **: gtk_combo_box_append_text: assertion `text != NULL' failed I tried the same procedures to build the CVS and it seems OK under Ubuntu 11.04. Is it related to gtk* something? Thanks, Yi-Nung Yang
