[gnome-schedule] GUI behaves wrong

Binary package hint: gnome-schedule

Just installed gnome-schedule v1.0, by using Synaptic, on an Ubuntu Edgy amd64. Greek locale

I noticed the following bad behaviour of the GUI when running as a plain user:
I insert a new task. It doesn't make any difference if it is recurrent or once. I press OK and I can see again the list of the scheduled tasks.

- Isn't the user meant to be asked for giving their root password?

- Every ten seconds, a new line appears in the tasks list, as a copy of the last inserted task. The list is getting longer and longer. If I reboot the program, I get only one instance per task. If ran from a terminal, there is once a gtkWarning:

/usr/share/gnome-schedule/mainWindow.py:249: GtkWarning: gtk_list_store_remove: assertion `VALID_ITER (iter, list_store)' failed
  self.treemodel.remove(iter)

and every ten seconds:

no crontab for user

- The column of "Date Time Settings" displays "On Friday at Feb" no date, no time.

- When a task on the list is focused, the "properties" and "delete" buttons on the toolbar OR the menu should work. Instead:
a. When I click on the "properties" button, I get a popup "Please select a task" but the task is always selected! Therefore the tasks cannot be edited.
if ran from the terminal, there is the error:

Mon Feb
local variable 'hour' referenced before assignment

b. When I click on the delete button, I am asked for a confirmation, but then the task stays were it was, on the list. If I reboot the program, it is THEN that the task is removed off the list. No error displayed on the terminal

- I don't know if this is meant to be hapenning, but no entry appears in the crontab (obviously cause it is an anauthorised user, nobody asked for a password). Events don't happen.

if gnome-schedule ran with sudo:
tasks are not displayed in the list. No error popup is displayed, but if I check the terminal window there is a "no crontab for root" notification:

ALSO, these bugs occur for both authorised and unauthorised users:

- Help > About: There is a popup displaying the version. The close choice on the button or the window menu does nothing, the window stays there... If I click on the other button (i think in the english locale should be sth like attribution) then all buttons halt and are not any clickable.

- Help > Manual: doesn't exist, could not find files.

- Icon gets installed in Application menu instead of System menu
