Bug#318517: crash on properties, when properties-dialog closed by "x"-button before

[bugreport]

Package: gnome-applets
Version: GNOME2.8.3
Distribution: Debian 3.1
Severity: critical
Gnome-Distributor: Debian
Synopsis: crash on properties, when properties closed by "x"-button before
Bugzilla-Product: gnome-applets
Bugzilla-Component: stickynotes
BugBuddy-GnomeVersion: 2.0 (2.8.1)

Description of the crash:
Stickynotes crash, when trying to reach the properties of a note, if you've
closed this notes properties-dialog before by clicking the "x"-button (while
the same procedure works as expected with the properties-dialogs own
"close"-button).

Steps to reproduce the crash:
1. open properties of a note-window (e.g. doubleclick its titlebar)
2. close properties-dialog by clicking "x"
3. try to reopen the properties of this note

Expected Results:
Accessing the properties, just like it works, when closing the properties before
with the close-button in the dialog itself. All methods of invoking the
properties end up in (the same?) crash, after closing properties once by a
clicking "x".

How often does this happen?
Everytime I try to access the properties, after closing them before by means of
the "x"-Button.
