The promotion action of "Trigger parameterized build on other projects" is not actually triggering another build upon promotion.
The promotion status says "successfully promoted" but no job is started.

----The promotion console output:
Started by user jm
Building remotely on auto-driver4
Promoting C-00-Build #236
build hudson.plugins.parameterizedtrigger.BuildTrigger@57197bee SUCCESS
Notifying upstream projects of job completion
Finished: SUCCESS

Note that if I switch to the plain "trigger another job" action it works correctly.
