Comment 4 for bug 1785622

I can confirm this issue. I also upgraded from 16.04 to 18.04 and instead of Dropbox icon I have now question mark without dropbox menu. I also can't start dropbox from application menu using command dbus-launch caja-dropbox start -i. It only starts with ~/bin/dropbox.py start command, which I found in another web page.
It is especially nasty because dropbox sent notification that only Ext4 will be supported starting with November and I have dropbox files on Ntfs partition and there is no way to change settings without GUI. I would be very thankful for recommendation on how to change dropbox settings in this situation.
