I don't have the IEEE document class, so I changed that to scrartcl. The document works fine, I do not get a babel error:
Package: babel 2004/11/20 v3.8d The Babel package
(/usr/share/texmf-tetex/tex/generic/babel/english.ldf
Language: english 2004/06/14 v3.3o English support from the babel system
(/usr/share/texmf-tetex/tex/generic/babel/babel.def
File: babel.def 2004/11/20 v3.8d Babel common definitions
However, this sounds a bit related to bug 36145. Can you confirm that you use the dapper-updates version of tetex-base? If so, does it work if you use scrartcl instead of the IEEE document class?
