When you introduce some special character into Breadcrumb-Separator you get an error in Flamingo Theme Editor

Steps to reproduce:

• Edit the current Theme
• Go to Breadcrumb Variable
• Introduce a special character to breadcrumb-separator (e.g. *, @, %, (, ) )

When I introduce "*" into breadcrumb-separator the theme disappears (See the picture Selection_005 ). Use also CTRL+F5 to see the changes.
