Traditionally, the original store-based binary rdb format was used for 
both "types" files (storing information about UNOIDL entities) and 
"services" files (storing information about UNO components).  Both those 
kinds of rdb files have since been changed, using a different binary 
format for the "types" files and an XML format for the "services" files. 
  Somewhat confusingly, all those kinds of files still use the ".rdb" 
extension.

unoidl-read can read "types" files (both the old and new binary 
formats), but not "services" files (the XML format)---and 
workdir/Rdb/pyuno.rdb is such a "services" file.
