Thanks for reporting it.
This is currently fixed in the upstream repository.
The last usermod call will raise an error and request the /etc/gshadow
file to be cleaned with grpck:
Multiple entries named 'tr' in /etc/gshadow. Please fix this with pwck
or grpck.
usermod: error adding new shadow group entry
I still need a few weeks (2?) before the next upstream release to prepare
a snapshot and call for translations.
I don't think this bug is that critical. I doesn't cause any corruption,
and it occurs only in case of configuration errors, which do not appear if
the administrators use the recommended tools for user/group
administration. Thus I will not issue a fix for this bug.
Also, I don't think it is worth doing a update for Etch.
Any other opinions?
