traceback on accepting invitation

[sascha_silbe]

Priority set to minor because there's no apparent effect except for the traceback itself.
Also filed as Debian bug #511894 [1].

Upon accepting an invitation, the following traceback will occur (on the machine accepting the invitation):

Traceback (most recent call last):

File "/usr/lib/python2.5/site-packages/sugar/graphics/animator.py", line 66, in _next_frame_cb

animation.do_frame(current_time, self._duration, self._easing)

File "/usr/lib/python2.5/site-packages/sugar/graphics/animator.py", line 92, in do_frame

self.next_frame(frame)

File "/usr/lib/python2.5/site-packages/sugar/graphics/palette.py", line 728, in next_frame

self._palette._hide()

File "/usr/lib/python2.5/site-packages/sugar/graphics/palette.py", line 564, in _hide

self.menu.set_active(False)

AttributeError: 'NoneType' object has no attribute 'set_active'

This seems to be due to calling _hide again after destroy_cb. Custom debugging output, filtered on the instance the traceback occured on:

init: self = <ActivityInvitePalette object at 0x9c296e4 (SugarPalette at 0xa01c2e0)>, self.menu = <_Menu object at 0x9c29acc (SugarPaletteMenu at 0xa027210)>
_hide: self = <ActivityInvitePalette object at 0x9c296e4 (SugarPalette at 0xa01c2e0)>, self.menu = <_Menu object at 0x9c29acc (SugarPaletteMenu at 0xa027210)>
destroy_cb: self = <ActivityInvitePalette object at 0x9c296e4 (SugarPalette at 0xa01c2e0)>, self.menu = None
_hide: self = <ActivityInvitePalette object at 0x9c296e4 (SugarPalette at 0xa01c2e0)>, self.menu = None

Stack trace from the destroy_cb call:

traceback.print_stack()

The self._palette._hide() call belongs to _PopdownAnimation:

class _PopdownAnimation(animator.Animation):

def init(self, palette):

animator.Animation.init(self, 0.0, 1.0)
self._palette = palette

def next_frame(self, current):

if current == 1.0:

self._palette._hide()

Looks like this animation object should be destroyed as well when removing the invitation.

I think Aleksey fixed this one recently, can someone check?
