Lines 174 to 177 in 555b322
// add some default binds and mounts to ValidVolumes
rc.Config.ValidVolumes = append(rc.Config.ValidVolumes, name)
rc.Config.ValidVolumes = append(rc.Config.ValidVolumes, name+"-env")
// TODO: add a new configuration to control whether the docker daemon can be mounted

Seeing that all cases where this fail happens is with multiple containers, I suppose there is a race and the run context is modified by two containers, only one of which gets in the list.

Let's hope #849 fixed it and re-open if it surfaces again.
