Ok, I think I've resolved this now.

In all cases I could find, the problem appears to be that sending an
empty diff to apply-textdelta does not work over libsvn_ra_svn and
libsvn_ra_dav, but it works fine over libsvn_ra_local. The exception is
not always raised from the right location because it is sent
asynchronously (as not every editor operation is confirmed by the
server).

Cheers,

Jelmer
