The only problems we're currently having with 64-bit are related to 
the "lib64" prefix that some distributions insist on using for the 
system-default libraries, instead of plainly "lib". (I wonder if those 
distros use the nonsense lib/ia64l64 that Intel invented for IA-64)

As you can see from the signature in queryAuthInfo, the last two 
parameters are "long int". You were passing "int". That's why it wasn't 

On D-Bus, this would have generated an error on all platforms. For one 
thing, the dubious type "long" isn't present in QVariant, so you're 
forced to choose between int (always 32-bit) and qlonglong (always
