Hi,
I just got hit by this bug, but I found an easy work-around that can help for the fix.
In my (complex) configuration, I have a parameterized job that triggers another one using the parameterized trigger.
To simplify the configuration I use the parameters set "Current build parameters", which ends up sending to the triggered job more parameters than what it actually accepts.
With Jenkins 1.500 and Rebuild 1.16 it worked, but now I'm using Jenkins 1.505 and Rebuild 1.18 and it does not work anymore.
If I modify the configuration of the job I'm triggering to add dummy versions of the missing parameters, then the rebuilding works again 
I hope it helps.
Cheers
Marco
