I haven't been playing EQ for a few months now, and unfortunately, all the computers with EQ installed aren't running atm, or I'd check out your suggestion and an idea, I'm thinking may be causing the profile problem.
Lucy has been misreading item info for quite a while (probably since the profile problem started). It could be the characters that don't upload have the bad items on them? Without doing alot of research it seems to be certain items with clicky, worn, or focus effects.
Google search, but there are way more than this short list:

A better search, but still way short:

Even if this isn't the source of the profile problem, it's another bug to look into.
Hope this helps some,
Yther Ore.
