Playing with alacarte, I have reproduced the bug again, but I can't do
it every time :( The problem has come turning off the Preferences item
on System. Also, there are more lines in the crash to help:
** (alacarte:32158): CRITICAL **: gmenu_tree_ref: assertion `tree != NULL'
failed
Traceback (most recent call last):
File "/usr/lib/python2.5/site-packages/Alacarte/MainWindow.py", line 419, in
on_item_tree_show_toggled
self.editor.setVisible(item, True)
File "/usr/lib/python2.5/site-packages/Alacarte/MenuEditor.py", line 209, in
setVisible
menu_xml = self.__getXmlMenu(self.__getPath(item), dom, dom)
File "/usr/lib/python2.5/site-packages/Alacarte/MenuEditor.py", line 467, in
__getPath
path = menu.tree.root.get_menu_id()
AttributeError: 'NoneType' object has no attribute 'root'
Although called by another method, the bug happens again in __getPath,
on trying to access to the 'tree' property of the menu (the 'menu'
variable can be also an item). It is supposed that every 'gmenu' object
must have a 'tree' property, but in this case this property is null.
Besides, the assertion fail tells it too.
