Document Classes ⇒ possible conflict between beamer and memoir?

[fvelde]

Hello,

for a while now I have been writing articles and preparing slides from the same main file, using the technique presented in section 21.2.2 of the Beamer manual, along with the memoir class.

I have been recently upgraded from MikTeX 2.6 to 2.8 and now problems arise.

Under v2.6, with memoir 2005/09/25 v1.618 and beamerarticle 2007/01/28 rcs-revision 1.6, the following code:

Code: Select all

\documentclass{memoir}
\usepackage[noxcolor]{beamerarticle}
\input null

compiles without problem (that is, I reach the * prompt).

Under 2.8, with memoir 2010/08/22 v3.6f and beamerarticle 2010/05/01 rcs-revision 7063f09e9019, the very same code results in the following log (edited for brevity):

This is pdfTeX, Version 3.1415926-1.40.10 (MiKTeX 2.8) (preloaded format=pdflatex 2010.9.16) 17 SEP 2010 16:31

Any ideas?

It turns out that beamerbasetitle.sty was missing a \providecommand for \titlepage. This should be fixed, I am told, within a few days. Problem solved.
