[NTG-context] Bug(?) in https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages

Hi, In https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages the wiki has "internal error: convert failed". Removing \color[red] from \setuptabulate in that example gives a working example (at least in a separate file on my machine). I tried changing the title specification to title={\color[red]{Fenchurch St. Paul}}, as well as title={{\color[red]{Fenchurch St. Paul}}}, but both of these reward me with a runaway context process. Can someone point out the correct way to do what the wiki intended? Thanks. Jim P.S. Bonus question: should an incorrect use of color really cause an (apparent) infinite loop, or is that a second issue which deserves to be on some to-do list?
