Promotion plugin does not run parameterized builds

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.
