This is the old zope DTML bug which the infamous antidecap kludge was introduced to work around. I think I was wrong to believe this fixed in zope 2.4. Re-enabling the kludge for all zope versions, as of zwiki 0.9.10.

update:
# DTML's decapitate() moves an initial block of lines that
# include : into the HTTP header
# workaround: keep a comment in front to hide them, strip it
# everywhere else (_set_text, read, ...).
#if ZOPEVERSION < (2,4):
# t = '<!--antidecapitationkludge-->\n\n' + t
#else:
# pass
# I thought this had been fixed in zope 2.4, but no longer
# furthermore, the old kludge no longer seems to be enough
# NB saving page text in the ZMI strips a leading blank line,
# including an invisible one that can prevent the above
# try this variant
#t = '\n<!--antidecapitationkludge-->\n\n' + t
# nope, no good
# I give up :(. It's not worth my while to figure this out.

NB this bug affects only the
structuredtextdtml and htmldtml page types in zwiki versions <= 0.9.9, and the dtmlstructuredtext page type in zwiki >= 0.9.10.
