Many thanks for that.

I've committed another fix for SearchUtils so please get revision 1.23 
and try again. Hopefully all 61 will no longer be >1, but if any are 
please send me sample blast files again.

For anyone interested, the bug was due to a completely unbelievable 
oversight on my part in the contig merging algorithm: I forgot to deal 
with contigs that were fully contained by others. Wow!
