[Lucid] In KDE, checkbox hangs with zombie kdesudo

Binary package hint: checkbox

Since latest checkbox update (well, previous versions did run, but ended in a bad crash at report sending time...) checkbox won't start in KDE anymore.

When starting checkbox I get a KDE prompt for administrative password, then checkbox hangs forever at "Gathering information from your system" step.

ps fax shows there's a zombie kdesudo process that checkbox did't process, and that's probably (I guess) the KDE admin password prompt. i.e.:

 5816 ? S 0:00 \_ /bin/bash /usr/bin/checkbox-gtk
 5818 ? Sl 0:02 \_ python /usr/share/checkbox/run /usr/share/checkbox/configs/checkbox-gtk.ini
 5822 ? Z 0:01 \_ [kdesudo] <defunct>
