It looks like the catalog export fails, then it fails again trying to write the error message. It looks like bad d开发者_StackOverflow社区ata, but we can't find anything. Anyone seen this before?

Have you tried exporting the catalog using the Catalog manager? The log would tell you where the bad data is, or at least it would give you a clue.

I agree it looks like bad data, do you have multiple languages in your catalog?
