I am having some serious problem with a document that uses both xetex and polyglossia. Compilation breaks with the following error (from the log):
! Undefined control sequence. <argument> blx@lng@\bbl@main@language The document compiled perfectly last year (It is a grant application, so I can pinpoint exactly when I successfully compiled it last: 8/15/2013) I was using TeXLive 2013 at the time, I am now on TL 2014. A Google searche [1] seems to indicate that this is sometimes due to a recent problem in biblatex---when the polyglossia command \selectdefaultlanguage is missing, biblatex fails silently and result in the quoted message in the log. However, this is not the case for my document: LyX correctly inserts a \selectdefaultlanguage in the exported (Xe)LaTeX file. Yet the error results. I tried exporting to LaTeX and compiling from the command line and of course I got the same error message. *However*: if I hit 's' and force XeLaTeX to continue, everything goes fine, and the resulting pdf is perfect. Anyone has a clue of what may be wrong?
