You could subclass FileUpload to add WithProperties support.  You can  
do this right from your master.cfg:

from buildbot.steps.transfer import FileUpload
from buildbot.steps.shell import WithProperties

class FlexibleFileUpload(FileUpload):
     """Enhances FileUpload to add "WithProperties" support on  
filename arguments"""

     name='upload'

     def _interpolateFileName(self, fileName):
         if isinstance(fileName, WithProperties):
             return fileName.render(self.build)
         return fileName

     def start(self):
         self.slavesrc = self._interpolateFileName(self.slavesrc)
         self.masterdest = self._interpolateFileName(self.masterdest)
         FileUpload.start(self)

[...and, later in your master.cfg...]

f.addStep(FlexibleFileUpload(slavesrc=['somefile'],  
masterdest=WithProperties("somefile-%(slavename)s")))

P.S. I tried this on my slightly hacked-up copy of 0.7.6 and it  
worked.  I see from another thread that you're running 0.7.5, so  
YMMV.  You'll certainly need to change the way I called addStep back  
to the form that 0.7.5 used.
