Add support for Babel 1.0dev

[Christian Boos]

Currently, it seems that using Babel 1.0dev (bl:source:trunk) is problematic, as we get the following:

AttributeError: NullTranslationsBabel instance has no attribute 'isactive'

as soon as we try to access any translation and there's no message catalog for the currently selected locale.

Hello ;

We are getting same error with trac 1.0 and Babel (last trunk). Please, can you fix it ASAP ? For now, We have disabled translation feature by removing babel but it's really annoying…

Btw: It's a bug, not an enhancement !

[Christian Boos]

Could you please test the fix proposed in #10903? If that works, that would be an extra motivation for applying and closing both tickets ;-)

[Jun Omae]

The same issue happens on Trac 0.12-stable with Babel trunk if vi locale.

I've posted the proposal patch on comment:5:ticket:10903. I verified the fix on Trac 1.0-stable and 0.12-stable with Babel trunk and 0.9.6.

Replying to cboos:

Sure, I'll test on our Trac instance (​http://trac.i-mscp.net). I'll report my feedback ASAP.
