cbt fails if cbt checkout directory not clean

I guess I had a pretty old version of cbt lying around, so I did a git pull. At that point I was stuck, since running cbt failed to build, as follows. (it came back to normal after a git clean -fxd):

Any idea what could be causing this? Is this something cbt could easily fix or it that something that's better fixed in zinc?

[dragos]

I'm not so familiar with Zinc, but it looks like the incremental compiler was confused. What made it worse was that I couldn't run cbt clean, I had to resort on git clean.

[cvogt]

I think this is something we'll have to monitor going forward. You are not the first one who ran into this problem and it's not that obvious. Maybe there is some smart way to avoid this after upgrades.
