Stud logo geometry has spurious sharp-marked and bevel-weighted edges

[cjhendrix]

This might be coming from the underlying ldraw geometry for the "LEGO" stud logo, I'm not sure. The bottom-left corner of the "L" and the top-right corner of the "O" have some edges that are marked sharp and have bevel weight of 1.0 . This prevents the desired bevels on any part with stud logos from having an effect.

If "clamp overlap" in the bevel modifier is deactivated, the desired bevels come back, but the stud logos get some crazy additional geometry in the two affected areas.

The image below shows the effected edges.

Looking at this a bit more, when I import stud4.dat by itself, all the edges are marked sharp with bevel weight = 1. So I'm wondering if ImportLdraw is using some kind of selection circle to grab those edges and clear sharp and bevel weight? And maybe that selection circle needs to be just a bit bigger?
