When I'm editing a text field and I click save, some extra characters get added. When I try to add a link for example it adds \" in front and behind the link area.

mailto:info@random.com
becomes
\"mailto:info@random.com\"

I first thought this must be a problem with tinymce but when I tried to adjust its settings (in the dashboard) and that text panel also displayed the same problem...

theme : concrete,
becomes
theme : \"concrete\",

(This of course happened across all lines)

Please help me out here. This has been bugging me for a while and I can't find a solution anywhere...
