Pierre,

the problem is with the NVO registry.  Its Registry Interface 1.0 
interface used to work, but it has been broken since mid-2010.  
Since RI is the only IVOA standard way to query registries, that 
is what TOPCAT uses, so at present all queries from TOPCAT to the 
NVO registry fail, reporting no resources found.  I reported this 
to NVO in August last year and the problem is acknowledged,
but there has been no fix.
