Ich habe mein eigenes Beamer-Klassen-Template geschrieben, das das boolexpr-Paket verwendet. Wenn man es jedoch mit dem biblatex-Paket kombiniert, entsteht eine 6 MByte große Logdatei und eine Menge Fehler. Die ersten sind

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

You're in trouble here. Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.

I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?
! Paragraph ended before \@secondoftwo was complete.

I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.

look up `weird error' in the index to The TeXbook.)

Basierend auf der üblichen Beamer-Methode zum Behandeln von Designoptionen könnte Folgendes eine Problemumgehung ohne das boolexprPaket sein:
\documentclass[screen, aspectratio=43]{beamer}
\setbeamertemplate{footline}{
\begin{beamercolorbox}{footline}
sdjk
\end{beamercolorbox}
}
\usetheme[style=vertical]{ntnu}
