Comment 1 for bug 1196253

Just experienced this myself, on my recently reinstalled Ubuntu 13.10 amd64 system. When I then tried the Dropbox package from the Dropbox website, of verison 1.6.0, I'm getting exact python-gpgme error on trying to verify the downloaded binary.

Possibly that this might be a python-gpgme bug instead, or that the Dropbox people have changed their download binary in some fashion.
