error using name "rebecca" on wiki-formatted regions

Using the name "rebecca" in wiki-formatted text-areas throws this error for me:

ValueError: invalid literal for int(): ebecca

This is because the parser is identifying changesets by looking for an "r" followed by numbers or 6+ digits of hex, which happens to be in Rebecca's name. My repository doesn't have a changeset matching "ebecca", so an error is thrown. I have no idea how this trac is mapping rebecca to r6621

I fixed this by adding an error handler for this case, see attached patch. I'm working from a freshly updated svn: ​http://svn.edgewall.com/repos/trac/branches/0.10-stable

The patch was created using: trac/versioncontrol/web_ui/svn diff > rebecca.patch
