os.listdir gives error if directories do not exist

First thanks for the script, after a few modifications it gave good results for me.

On first use I got errors from os.listdir because the directories it tried to list (revisions and attachments) don't exist for all pages. The script ended therefore with an error. After adding two lines:

admin = trac.scripts.admin.TracAdmin()
admin.env_set (wikidir)
revdir = moindir + '/' + page + '/revisions'
if os.path.exists(revdir):

revisions = os.listdir(revdir)
for rev in revisions:

cmd='wiki import %s %s' % ( page, revdir +'/'+rev)
print cmd, "->", wikidir

# Process attachments
attdir = moindir + '/' + page + '/attachments'
if os.path.exists(attdir):

attachments = os.listdir(attdir)
for att in attachments:

attachment = Attachment(admin.env_open(), 'wiki', page)
size = os.stat(attdir + '/'+ att)[6]
print "attaching " + att + ' = ' + str(size)
attfile = open (attdir + '/'+ att)
attachment.insert (att, attfile, size)

(the boldfaced lines), it worked fine.

I added a new zip file to solve the problem Marius already had and solved. I solved it on a different way, but i worked for me. I added "if os.access(revdir, os.F_OK):" instead of "if os.path.exists(revdir):". Would one please add it to the mainpage, so that every user use the old one.

Maybe if I send the latest modifications here as a patch you can directly apply to the repository it will get applied?
