Description:
"Automatically resolve redirects"-feature on Wikipedia API causes error with at least one particular page at Finnish Wikipedia (fi.wikipedia.org). I'm not sure whether this is a bug with the API or with the database.
The last time the feature worked correctly for me was on April 4th 2008.
The first time the feature gave me an error was on April 8th 2008.
