I checked, and CC-BY is not compatible with the GPL:
http://www.gnu.org/philosophy/license-list.html
so if you want your extension to continue to be tri-licensed, then you 
can't take her work under CC-BY.

I'm not sure what licence would be suitable. No licence permits the 
removal of accurate copyright information, so they all go that far. But 
most are focussed on making sure that people's names don't get used for 
endorsement, rather than explicitly protecting their right to a credit. 
If you have a licence which requires a credit, you start getting close 
to the BSD advertising clause:
http://en.wikipedia.org/wiki/BSD_licenses#UC_Berkeley_advertising_clause
which makes a licence non-free.

Perhaps the general copyright-law requirement to preserve copyright 
notices is strong enough for her? If so, she could either tri-license 
the work, or make it available under a BSD-like or MIT-like licence.
