Problem saving page/post with Nordic letter ö, ø in a element

Hi
I got some problem with Nordic letter ö, ø in the Content Element Accordion. I try to paste some text into a toggle area. (to the wysiwyg area) A text without ö/ø in the title

Here is the text that I put in (tried several times with and with out ø, and every time the ø is used in the accordion it crashes):
——–
The largest Nordic retailer of electronics, white goods etc.
Around 400 psychical stores, 5 web shops and 9100 employees
Head quarter in Lørenskog, Norway, and warehouses in Norway, Denmark, Sweden, Finland, Iceland, Greenland and Faroe Island
Elkjøp webshop: http://www.elkjop.no

Then save the element works but not save the Portfolio Item/Page or Post. The “saving Avia layout builder wheel” is spinning and never stops…

Any ideas how to fix this bug?
