Non Latin-Characters in Location prevent publishing of post

[GoogleCodeExporter]

WP 4.0.1
GeoMashup 1.8.2

When using the map or the search box to provide a location for a page or post, 
the following problem occurs:
When adding a location for example in China, the location is found. After 
pressing publish the next page does not load, the page or post is not saved.
With names like London or Berlin, there's no problem.
