"LaTeX3 Error: Command '\textsi' not yet defined!"

Thanks. Is there a way to stop LaTeX3 from compiling the file? In fact, independent of using or not using this package, since starting to use Lyx again a day ago, no matter what I compile, I periodically see the message "L3 Programming Layer <date>" on the status bar at the bottom of the Lyx window.

In the interval, a problem has arisen, though nothing has changed in my setup besides updating Lyx and Latex via TexLive. I install the embrac package, which ensures non-italic brackets in otherwise italicized environments. This used to work without a problem, but now generates the error message:
LaTeX3 Error: Command '\textsi' not yet defined!
I am sure of my trouble-shooting, since commenting out the usepackage command eliminates the error.
This is pretty suspicious. It suggests, to me, that LaTeX3 is being used to compile this file, which will almost certainly cause major problems with LyX. Then again, it's possible that the problem is just local to the embrac package. You might try writing the maintainer at contact at mychemistry.eu<mailto:contact at mychemistry.eu>.
