I fixed one MoreData probelm in revision 383. libsyncml 0.4.6 is from
revision 342. I don't know if this fixes all problems. I only fixed some
kind of a state management problem. Which comments do you mean?

Ticket #1.

Ticket #2.

I use photos in my contacts and so I test this stuff every time I
synchronize my mobile :)

Nevertheless I'm really interested to fix such bugs. Can you please open
two bugs on http://libsyncml.opensync.org/ (you must register and login
before you can do this)?

BTW actually the ticket mailing list does not work for this tracker but
a ticket is persistent and I cannot ignore it silently ...

Best regards
