Comment (by WraithKenny):

 I've had issues with this, and couldn't figure out the proper solution.

 Support forum issues are usually resolved (or abandoned) with vague
 explanations that plugins are doing it wrong. As a plugin developer that
 IS doing this wrong, it's really not helpful since it's extremely hard to
 figure out what I'm actually doing wrong, since there exists no good
 explanation of the problem, nor any best practice tutorial for doing it
 right (what ever that may be). The only thing I do know about this issue
 is that sometimes the length of serialized meta is wrong do to line-
 endings. (Why the line-endings are sometimes CR/LF I haven't been able to
 trace, but think it's do to ajax saves, in my plugin at least.)

 My feeling is, if you are using the correct APIs and sanitation practices,
 something like this shouldn't happen: there should be no extra unknown
 step for plugin developers to do (like say normalize all line-endings
 prior to update_option/_post_meta? No idea if that'd work, and that's the
 point: There's no community education around this issue). I'm sure the
 majority of authors have no idea if the exporter/importer works with their
 meta.

 Anyway, if this is a plugin developer problem, some guidance would be
 appreciated, if not, a bug fix would be appreciated.
