Bug#627060: python-debian: successive calls to GpgInfo.from_sequence() remember gpgv args

[Julien Cristau]

Package: python-debian
Version: 0.1.18
Severity: normal

Calling GpgInfo.from_sequence() results in gpgv argument being appended
to the previous args.  Example:

$ strace -f -eexecve python
execve("/usr/bin/python", ["python"], [/* 38 vars */]) = 0
Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48)
