As far as i can tell, this problem does not exists in the head version of xowiki+xotcl-core. just now, i have created 2 pages, where the 2nd one contains the first one. Clicking on "view" in "revisons" on the page including the 2nd one works fine.
Note, as indicated before, an updated xotcl-core is not sufficient, xowiki should be updated as well. Note that the mentioned patch was between xowiki-procs 1.122 to 1.223. xowiki-procs is in head at version 1.306.
Not sure, what xowiki version you are using. It might be easier to upgrade xotcl-core and xowiki to HEAD.
