After import with v.in.ogr, overlapping parts have a category value set in layer 2. If you want to get rid off all overlapping parts, check with v.category op=report if any centroids still have a category value in layer 2. Sometimes these areas can be cleaned away with v.clean tool=rmarea, sometimes manual editing with the vector digitizer is needed.
Markus, I have seen that overlapping parts are assigned cat 2, but did not know what to do about it. The warnings left after importing with v.in.ogr are: WARNING: Number of incorrect boundaries: 39934 WARNING: Number of centroids outside area: 528 WARNING: Number of duplicate centroids: 107 and I've looked at the v.clean tools (and the wiki page) trying to find the appropriate ones. I tried 'v.clean -c tool=break type=line' which runs rmdupl after breaking and rebuilding topology, but v.proj reports the above warnings. I'll check v.category first, then read the 'See also' references at the bottom of that wiki page.
