Not sure if there is a bug in mkgmap or not, but the data in 
OSM is clearly not Ok. The address exits twice at the same place:
once with addr:city=Ottobrunn, once with addr:city=Hohenbrunn.
So maybe mkgmap creates both address records and you only looked
at the wrong one?
Since everything except this single address is tagged with 
addr:city=Hohenbrunn and the house is inside of the address
boundary of Hohenbrunn, so the addr:city=Ottobrunn looks wrong to me.
