The command was:
$ hg convert --filemap cantroid_filemap -A cantroid_usermap cantroid
cantroid_cleaned

Using:
$ hg --version
Mercurial Distributed SCM (version 1.3.1)

OS is debian/lenny x86, 2.6.32 bpo kernel.

The same conversion went flawlessly before, the only change I made was
adding the following 4 lines to the filemap:

exclude dbgen/backups/tdammers_topia.sql
exclude dbgen/backups/tdammers_cantroid.sql
exclude dbgen/backups/tdammers_cantroid_partial.sql
exclude dbgen/backups/tdammers_cantroid.sql.gz
