Distribution/Version: SuSE 9.3

I have selected my GroupWise system addressbook and "Frequent contacts" for
autocompletion. When I try to enter any email address in a composer, I see a
huge memory built-up in the EDS process.
In this specific case:
- Start Evolution (EDS is 14MB)
- Open a composer window (20MB)
- Type pgoel@novell.com in "To" (91MB)
- Type another pgoel@novell.com in "To" (170MB)
- Another pgoel@novell.com (255MB)

Basically, for every new email address that I am entering, it increases by
70-80MB. After entering 7-8 times, my machine became unusably slow, so that I
could not even kill evolution to resume work.
