AttributeError: 'NoneType' object has no attribute 'group'

[Russ Tyndall]

I keep getting the error below intermittently. I am running 4 trac instance using this plugin and randomly, they will each fail occasionally with the message below. They seem to work great when not showing this error. I have done everything I could think of to remove any old version of the plugin on the system, so I dont think that is the problem.

I also tried updating to the head trac10 revision, but when I tried, it would not compile (see second error below).

This is pretty important because I have a class full of software engineering students trying to register users and login and occasionally that process just fails inexplicably. I have 'fixed' this problem briefly by resetting the webserver until it decides it wants to work again.

I am running trac 10.5 Python 2.4.4 TracAccountManager-0.1.3dev_r2548-py2.4.egg Using a htpassword file for auth

Thanks in advance for your help resolving this matter,

Russ

ps. thanks for the great plugin, it is really nice when it is working!

This error seems to have been caused by it being installed as an egg in the local plugins directory rather than globally, though I couldn't tell you why.

I still cannot build the latest revision for the trac 10 branch

You need to build it from an SVN checkout since it's configured to append the current SVN revision to the version number of the package.
