Rails 3.0.3, Ruby 1.9.2 on a Windows 7 machine

Same issue here. I believe it's because the tmp file isn't being closed properly, and Windows won't allow it to be deleted.

EDIT:

Looks like it's been fixed in Carrierwave version 0.5.3 (see Changelog)

I'm still getting that error on Windows, even with CarrierWave 0.9.0. I work around it by not testing it in development, rather push it to Heroku and use file uploads on my site, see if anything breaks. It seems to be fine.

Since my Windows laptop is nearing the end of it's useful life (too slow), my next solution to this issue will be to wipe this computer, install a lightweight version of Linux, and see if that not only fixes the issue in development, but also extends the useful life of my machine.
