gs_import_osm not tolerant to preexisting indices

[msoulier]

Following the instructions at http://bmander.github.com/graphserver/ I am trying to integrate GTFS and OSM data.

When running gs_import_osm on my osmdb file, it works for a while and then fails.

100201/103282 edges loaded
101234/103282 edges loaded
102267/103282 edges loaded
103300/103282 edges loaded
indexing vertices...

Seems like that exception should just be caught. Ok, it exists. Move on.
