Bug#821927: basename: missing operand

[Herbert Parentes Fortes Neto]

Package: gdm3
Version: 3.20.1-1
Severity: important

Dear Maintainer,

 I did an 'apt-get dist-upgrade' and end with this:

# LANG=C apt-get dist-upgrade
Reading package lists... Done

Setting up gdm3 (3.20.1-1) ...
basename: missing operand
Try 'basename --help' for more information.
dpkg: error processing package gdm3 (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 gdm3


Seems to be the same error reported in bug #579103 (2010 - squeeze/sid)
