TypeError: Object #<Object> has no method 'removeListener'

[balupton]

Been getting these errors a lot since v6.25.0 on the balupton and docpad websites. Need to be fixed, but I'm not yet sure what is causing the problem.

[slindberg]

If it helps, I only started getting these errors after upgrading to node v0.10.0 (previously on v0.8.18).

[balupton]

Hrmm.... I haven't gotten these errors with 0.10.1, how about you?

[slindberg]

I upgraded to v0.10.1 this morning and have still seen a couple of these error go past.

[balupton]

Looked into it, the error is definitely thrown in the node code - it points to the removeListener call within the once call. Will look into it to see if the fix is within us, or Node.

[balupton]

Fixed/worked-around the node.js change in bal-util v1.16.13

Reinstall docpad with the -f flag and you'll be good to go.
