Summary:                    switch on uninitialized variable
Description: 

When parsing a query "SELECT ?s WHERE { ?s ?p ?o . }", I get these warnings:
  Variable p was bound but is unused in the query
  Variable o was bound but is unused in the query

This is fine. But there's an issue logging the warning in redland. When using 
only rasqal, there is no problem, but when using redland there is a jump that 
depends on an uninitialized variable in  librdf_log_simple().

I've attached two programs., rasqalwarning.c and redlandwarning.c. The latter 
shows the problem when run in valgrind with the latest versions of redland, 
rasqal and raptor.


Steps to Reproduce: 
- compile redlandwarning.c with redland
- run it in valgrind
- observe the error message in valgrind
