Failed to install with Trac 0.12

[tjb@…]

Just created 2 new trac projects, and went to install the TiminsAndEstimation plugin. We already use this plugin on other projects. The trac-admin <envname> upgrade failed with this error message

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

We have recently upgraded to Trac 0.12 - as released a few days ago. Have previously been using 0.11 with this plugin, and 0.12dev (various revisions) with this plugin too, including installing in new projects

I have not upgraded to trac 12 yet, and therefore cant help, you. I had not realised that trac 12 had released. I will try to get a new working version of the plugin up soon.

Seems related to: ​http://trac-hacks.org/ticket/7262 Starting a 0.12 branch now

(In [8124]) First trac-12 version, changed db access to not close databases (now that its not good to do so) re #7259

[Russ Tyndall]

While this will allow you to get those projects upgraded, there are probably still trac 12 incompatibilities I am working on fixing (like #7055)

(In [8125]) first trac12 version 0.2.3, removed db.close calls for trac 12, so that this should be able to update and use the database again re #7259

Thanks for the quick response - I will try it out out today.
