[reportlab-users] Re: broken code

Re: reply from Robin Becker in reply to my posting (at foot):

hi, we've not moved to 2.3 in any great weight yet so this could be of
use. Do you have a minimal example that gives this error? Can you run
with the same code and Python-2.2.3?
++++

Initial reaction: I don't think this can be a 2.3 problem -- the previous
box was running 2.3 also, so unless the previous installation managed to
access 2.2 in some weird way (that machine had both, the new server has
only 2.3) this is more probably a case of the code running with Reportlab
approx. 1.16 with Python 2.3, but not with RL 1.18. 

I'll try to run some tests to whether this is in some way data-specific
(doesn't look like it) and fiddle with various versions, but this may take
a little time (urgent though it is).
