Menu Icon implements 45x45 as default

Hello.

Selecting the default image style in menu icon settings gives no result for me in both .dev and beta1 versions of the module (I have cleared cache), the standard 45x45 being used as default (if default selected).

If I select the custom style directly in menu item form it seems to work, but in css image is added with corrupted path like "/public://sites/default/files/menu_icons/menu_icon_1.png". When the standard 45x45 applied the path is normal "sites/default/blah-blah...".

Maybe someone had such an issue or some other modules could affect menu icons?

Any ideas would be appreciated.
