Why not assigned to you after reported it ?

[Gilles Dubreuil (gdubreui)]

Yeah I guess I must take it.

[Gilles Dubreuil (gdubreui)]

Giving back ownership because I shouldn't have taken it in first place, I made a fix but I don't know much about the testing framework and tox and not sure I'm going to have the bandwidth to dig into it ATM.

@gilles, sorry if we discouraged you. IMO the patch was almost done, i'll take over if you want, but i don't think there was much work left

[Gilles Dubreuil (gdubreui)]

@Steve,

Not at all, it's just that tox is not currently working on my environment. And I have other priorities (puppet/ruby)
I don't want to slow down the process.

Thanks.
