After quitting LyX, I see the following in the terminal:

Should I use a local patch to turn these into an assert and figure out how to 
reproduce?

Any takers? I now have a way to reliably reproduce and would be happy to
make a minimal example if anyone is interested in taking a look.

notes to myself for how to start making an MWE: I can reproduce using
the following on 433a97d6 of my private repository:

   cd 19-dots-and-lines/ && mylyx master-master -e xhtml dots-and-lines.lyx

I do notunderstand how our lib/*symbols files work, but this is suspicious:

fantomas (master): grep -i 27e8 lib/*symbols
lib/symbols:langle             cmsy        104 225 mathopen   ⟨
lib/unicodesymbols:0x27e8 "\\textlangle" "textcomp" "force" "\\langle" "" # MATHEMATICAL LEFT ANGLE BRACKET

U+27e8 is a mathematical left angle, why is it related to \textlangle?

This was introduced at 4ebb415773e. Günther, are you reading this, by chance ?

Scott, I do not know if the above is useful. I tried to reproduce your error, but cannot. Could you try to get a backtrace?
