[mkgmap-dev] Missing foot of T-shaped way

I was browsing the map today, and found out that a way is missing from the map: http://www.openstreetmap.org/browse/way/26652955 This is the entry of a dead-end residential street (or, the foot of the T). Shorter ways nearby do show up fine. Both the "hat" and the "foot" of the T carry identical tags, but only the "hat" is visible on the map. The "hat" does make a small knick where the foot should be attached. This is not near any tile border. Any ideas what might be wrong? Is the map tile simply too big? I will refine the map there to see what happens. Marko
