error when register as new user using an existing e-mail address

[hartenthaler]

When I try to register as a new user (enter data in "Request a new user account" and press the "continue" button) there is an error message from fancy-imagebar, if I'm using an already existing e-mail address. Normally webtrees will show the home page with an error bar that this e-mail address is already used. If fancy-imagebar is activated, this results in the following error:

This is already solved with this commit: 7927d16
