teps for reproduce:

Via a Sun Wikis user:

1) edit page in "Rich text" mode and create Link "Insert/Edit Link" (set alias)

2) striketrought (score out) these link (alias)

3) save

4) edit again (whatever you want) --> link will duplicate

e.g.: I created an example at: http://wikis.sun.com/display/g11n/Test+Page
