I've recently downloaded the app from Copy.com (a Dropbox clone). When I run it on Ubuntu 12.10 from the terminal, I get the following message/warning:
Expanded string ~/.copy /home/USERNAME/.copy
Expanded string ~/.copy /home/USERNAME/.copy
QGtkStyle was unable to detect the current GTK+ theme.
I know something is not working because the top bar icon of the app doesn't show. How could I fix this?
