Option labels not visible on filters select boxes

[Guido1982]

I've used the demo on http://corebos.org/demos/corebos/ and followed the following steps:

• Created a field for Organizations in the layout editor.
• Went to 'create filter' from the Organizations list view.
• Went to 'Advanced Filters' and opened the dropdown for field select.
  

And yes, I can see my newly created field here. I will take a look at the files, hopefully I'll get around to that today but I have to create a test-copy of the production server for this. This may have been caused by an update and only discovered later on, it's one of those little things you don't test after an update so who knows...
