vpr is null and you're dereferencing it.

InitPrintDrivers is passing in a NULL vpr because GetDimFuncAndRec isn't 
filling it in.  Which, presumably, is because either driverInits is 
zero-sized or because the driver name isn't matching.  Breakpoint on 
GetDimFuncAndRec and a little snooping should tell you which one it is.
