Plugin fails to function with missing name in session

[ahowell82@…]

I have an instance where the plugin does not function. There is a user in the session table that does not have a display "name". While the entry is in the session table, I will only see the spinning gif; once I remove the session entry, the plugin begins to function

trac-admin . session list:

Wired. The issue couldn't be reproduced to me with missing name.

It's not a possibility that the user_data list includes None. If Chrome(self.env).format_author(req, user) in the following code could return None, the evaluated value would be an empty string.

149         # user names, email addresses, full names
150         users = []
151         for user_data in self.env.get_known_users():
152             user_data = [user is not None
153                          and Chrome(self.env).format_author(req, user) or ''
154                          for user in user_data]
155             for index, field in enumerate((USER, EMAIL, NAME)):  # ordered by how they appear
156                 value = user_data[field].lower()

I consider you are using modified AutocompleteUsersPlugin. Please reinstall the latest.

I did no think I was utilizing a modified version of the plugin. I will re-install version 0.4.3 and report any findings
