just did a clean install of linux mint 14 cinnamon and installed nemo-dropbox hung at 100%
sudo dpkg -r nemo-dropbox
cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
sudo apt-get install nemo-dropbox
seems to fix the problem
i believe the newer deamon just needs to be added to the package but i dont really know how this stuff works
Does it still happen in Mint 17.x?
