Package: gksu
Version: 1.3.6-1
Followup-For: Bug #344103

hello,
every time I launch gksu, I have a blank error dialog box.
In my .xsession-errors, I have only the following error :

(gksu:22993): Gtk-WARNING **: Failed to set label from markup due to error parsing markup: Error on line 8 char 9: Invalid UTF-8 encoded text
