I continue my long discovery of bugs in Megamenu module...

I added an icon image to a menu item in "Menu item data" overlay.

• the item is not shown in the front-end. After fixing two typos in theme.inc (line 494 - image instead of iamge and title instead of titlle), icon is shown in the front-end.
• but it is not shown in the back-end after saving the form
• and if I add an icon image to another menu item, the image from the previous menu item disappear i.e. only one image is shown in my menu.
