See attached patch.

Can anyone think of any reason not to do this?

If it catches things like the python syntax error in anaconda for today's
rawhide compose, that makes installs impossible, then it is well worth it

Yeah, I'm for putting it in.  While it may cause a couple more
speed-bumps for the rebuild next week, it'll raise our quality in the
long run and therefore seems like the "right" thing to do

Indeed. Did a couple of basic smoke-tests: anaconda and yum (current F10 versions) pass without problems, and OTOH a deliberately caused indentation error gets trapped: Compiling /home/pmatilai/rpmbuild/BUILDROOT/anaconda-11.4.1.63-1.x86_64/usr/lib/anaconda/lvm.py ... Sorry: IndentationError: ('unindent does not match any outer indentation level', ('/usr/lib/anaconda/lvm.py', 44, 51, ' if not (os.access("/usr/sbin/lvm", os.X_OK) or\n'))

Building to rawhide right now (rpm-4.6.0-6.fc11), do holler if it catches something it shouldn't.
