[texhax] wrong at fontshape error

[Dan Hatton]

Dear All,

My prosper document, which will contain a few Cyrillic characters,
fails to LaTeX with the error message

wrong at fontshape ...message {Corrupted NFSS tables}
                             error at fontshape else let f...

This may be related to Debian bug #98998.

Any ideas, please?

A minimal(ish) document that exhibits the problem follows.

Thanks,

Dan
