How to Reproduce

While doing a POST operation on /admin/accounts/users, Trac issued an internal error.

(please provide additional details here)

The error can be reproduced when attempting to reset password for a specific user and occurs both from the Web Admin Panel & from the Forgot Password Form.

Method works for other users.

PluginIssue (​TH:AccountManagerPlugin).

Also, your Trac version is a bit dated. Upgrade to at least the latest minor release of that branch (TracDownload#LegacyStableRelease).
