Package: python-cracklib
Version: 2.8.12-8lenny1
Severity: grave
Hi,
the following (cut down) piece of code, part of db.d.o, runs on lenny,
but apparently not on squeeze:
wea...@intrepid:~$ cat h
#!/usr/bin/python
import cracklib
cracklib.FascistCheck('foo', '/var/cache/cracklib/cracklib_dict')
wea...@intrepid:~$ ./h
Traceback (most recent call last):
File "./h", line 4, in <module>
cracklib.FascistCheck('foo', '/var/cache/cracklib/cracklib_dict')
ValueError: it is WAY too short
But on squeeze:
wea...@byrd:~$ ./h

zsh: abort ./h
It does not die when one doesn't give a dictpath, but we use that feature.
Cheers,
