CKEditor preview not working (resolveuid)

I have a Plone 4.3.12 with collective.ckeditor 4.4.5.
If I add an image via "Image Plugin" the final URL is like

resolveuid/cd982d7c5a824d25834a88fea80abeaf/@@images/image/preview

The "Preview Plugin" can't display the images correctly.
Firebug console output:

"NetworkError: 404 Not Found - http://mydomain/Plone/++resource++ckeditor/plugins/preview/resolveuid/960eb309fe6e41d09ec8dfc34be9639c/@@images/image/preview"

How can I fix that?
Or maybe better: How can I add the base_url to the image URL ("http://mydomain/Plone/resolveuid/960...")

Thanks.

Hmmm...I read that (loo paper) topic. But what is the solution?
In my custom package I can modify CKEditor params like this:
overrides.zcml:

<browser:page
name="ckeditor_plone_config.js"
for="zope.interface.Interface"
class=".ckeditorview.CKeditorView"
attribute="getCK_plone_config"
permission="zope.Public"
/>

And here is the ckeditorview.py:

from collective.ckeditor.browser.ckeditorview import CKeditorView as BaseView
class CKeditorView(BaseView):
    """
    CKeditor overrides
    """
    def getCK_plone_config(self):
        res = super(CKeditorView, self).getCK_plone_config()
        return res

    @property
    def cke_params(self):
        params = super(CKeditorView, self).cke_params
        # for example...
        params['filebrowserBrowseUrl'] = "''"
        return params

This must not be a widely used package, so your best bet is to file an issue in the repo or contact one of the maintainers of the package.
