cannot share any docs in pages via mail

It seems I'm not the only one with a similar problem. As of this lunchtime I can no longer share a doc in pages (via drop down menue, share, email, pdf for example). Mail is still the default programme; all other parameters are exactly as they were this morning.

Is there a quicker way than exporting, that creates a new document and I really don't want to have most of my docs in pages AND word AND pdf, depending who I send them to. My Os is SL 10.6.8.

How do I get the sharing function to work again? Any help greatly appreciated!
