so can you please provide a lintian override for python-mysqldb at
/usr/share/lintian/overrides/python2.2-mysqldb and python2.3-mysqldb,
with the following content:

python2.2-mysqldb: possible-bashism-in-maintainer-script

and for python2.3-mysqldb:
python2.3-mysqldb: possible-bashism-in-maintainer-script

should i reassign this bug to lintian?
