This program still does not work on my ubuntu 8.10 x64.
The first time, it says if I want to replace the conf file with gadminproftpd one. I say yes, then I have :
(gadmin-proftpd:12992): Gtk-CRITICAL **: gtk_entry_set_text: assertion `GTK_IS_ENTRY (entry)' failed

Erreur de segmentation

I restart the application :
segmentation fault.

The package is now called gadminnnproftpd. I am running it with sudo.
