[mkgmap-dev] roadtrip no longer happy

I updated mkgmap to r1337, and found that my overview img/tdb changed names. I adjusted gmapibuilder invocation to reference those, and that succeeded. But on loading into roadtrip I get a "The map you selected contains some errors and cannot be displayed. The default map is being shown instead." popup. The test map fails more spectactularly, crashing roadtrip and then I have to rm it from ~/Library.... before I can start it. (script I used attached; test data was josm-downloaded bits of my town, and then cloudmade massachusetts.osm.bz2) Has anyone had recent success with roadtrip? I probably should try bisecting svn to find when this behavior started.
