propath option of PCTRun extends propath instead of replacing it

[GoogleCodeExporter]

What steps will reproduce the problem?
  1. define os environment variable propath
  2. create PCT run task to show propath (e.g. the attached showinfo.p)
  3. PROPATH is path set by task + os enviroment variable

What is the expected output? 
  Only the propath as set by the task

What do you see instead?
  The propath set by the task followed by the os-getenv("propath")


What version of the product are you using? 
  1.84

On what operating system?
  RHEL 5, OE 11.3

Please provide any additional information below.
I would expect the ouput of both commands to be the same

[CCE+cvb@cce-dev01 ant]$ PROPATH=/from_environment ant -f [CCE+cvb@cce-dev01 
ant]$ ant -f pct_issue_propath.xml

Not needed, I can get the behaviour I expect  by adding a
 <env key="PROPATH" value="" /> 
to the run config.
