Forum OpenACS Development: Minor XoWiki Error: /tag/Core?category_id=835073&summary=

Hi,

XoWiki returns an ugly error if the "summary" attribute is empty. To reproduce please go to:

https://openacs.org/xowiki/tag/Core?category_id=835073&summary=

Google Webmaster tools causes this issue in our www.project-open.org instance...

Cheers!
Frank
