It might be an e-TeX issue.

For trying whether it is an e-TeX problem, you would have to do the
following:

1. in /etc/texmf/fmt.d/00tetex.cnf, comment the line

pdflatex  pdfetex         language.dat    *pdflatex.ini

by putting "# " in front of it. There's still a line for pdflatex with
pdftex (without the e) above it.

2. Remove /usr/bin/pdflatex (a symlink to pdfetex)

3. Run update-fmtutil, texlinks, and "fmtutil --all"

This should create a new symlink /usr/bin/pdflatex --> pdftex and the
according format in /var/lib/texmf/web2c.

Then try the file again.
