Hi Felix,

Yes I know, in my own style I use extended non routable line types for those ways,  but I saw that in the default style this road was rendered ok.
So to reproduce this bug, I took the default style and removed the routable attributes on the trunk highways to see if the same would happen (which was true).
So the only thing that triggered the lines to disappear were the routable attributes, and Gerd found out that it also was related to the oneway directions.
