Absolutely.

I have no time to fix this now, but this is a regression, and I should
have taken care of it obviously. The management of the error message
is not as easy as it used to be in this case. I suppose we should
check whether the tree is "none" wherever we need to access it (in the
revision specifiers other than revno:N:path).
