LyX ⇒ Export to LyX archive fails

[krjackson]

I'm trying to export my project to a Lyx archive, but it fails with an error. The terminal shows:

Code: Select all

Running: python2 -tt "/usr/share/lyx/scripts/lyxpak.py" "/home/krjackson/Documents/"/"XRQuick.lyx"
Traceback (most recent call last):

Has anyone encountered this before? I'm by no means a LyX power user, so perhaps I've done something unexpected in the text. Google didn't return anything useful to me, and a quick search here didn't find anything. Any input or advice would be welcome.

Edit: I should also note that LyX is as close as I get to actual LaTeX. My LyX Version is 2.0.6, running on an Arch box. I'm using TeX Live from tug.org, not Arch's distro packages. Don't know that any of that is relevant, but there it is.

I have made a little headway, maybe. A friend of mine worked some magic with emacs and determined that position 1485-1486 mentioned in the error output is in the LyX header at the beginning of this line:

Code: Select all

\paragraph_separation skip

I don't know why that looks like a "truncated /uXXXX escape", but I don't know what a truncated escape looks like anyway.

Anyone have any ideas on where to go from here?
