R help - Dec 2006 - RODBC not working when connecting to a Sybase database

What is this error message about and how do I troubleshoot
it?
> sqlTables(channel)
Error in .Call("RODBCFetchRows", attr(channel,
"handle_ptr"), max, buffsize,  :
        negative length vectors are not allowed
The channel was created as such
channel <- odbcConnect("Labdata")
I think this is telling me that my odbcConnect command worked
> odbcGetInfo(channel)
