bug in convert

[Christoph Egger]

Hi!

I tried to convert netbsd anoncvs src tree into a mercurial repository.

I checked out a clean netbsd cvs tree and then started
the conversion with

   hg convert src src-hg

Conversion failed with:

794600 sys/arch/hpcmips/conf/GENERIC
794700 sys/arch/hpcmips/conf/GENERIC
794800 sys/arch/hpcmips/conf/INSTALL_TX3922
** unknown exception encountered, details follow
** report bug details to http://mercurial.selenic.com/bts/
** or mercurial at selenic.com
** Mercurial Distributed SCM (version 1.3)
** Extensions loaded: convert, rebase
