error message with User toolbars

My user toolbars goes wonky at the moment with the new Nvil version. I enter the edit mode, hover with the mouse over a button, the button turns into a red cross where there was a icon before, and i get a error message.

When i restart Nvil then it`s okay for a while. But after five minutes the error happens with other icons again then.

I hope i don`t have to redo the toolbars from scratch. It was really lots of work to get so far :/

Additional info, just found out that the affected buttons are the ones that are checked outside of the editmode.

See if fixed.

Confirmed as fixed. Thanks
