Special characters in passwords provoke an internal error

[jeberger@…]

Description

When adding a new user, if the password contains special characters Trac gives an internal error.

Steps to reproduce

1. Go to the "Users" administration page;
2. Create a new user, name="foo", pasword="é";

Version information

• Trac: 0.10.4
• TracAccountManager: 0.1.3dev
• Python: 2.5
• Firefox: 2.0.0.6 on Linux

Additional information

I get the following traceback:

Looks like a dup of #2327.
