Comment 5 for bug 127372

I can confirm this bug in debian testing amd64 with the following packages:
libthunar-vfs-1-2 1.0.1-3
libgtk2.0-0 2.18.9-2
thunar 1.0.1-3
thunar-archive-plugin 0.2.4-5
thunar-data 1.0.1-3
thunar-media-tags-plugin 0.1.2-2
thunar-thumbnailers 0.4.1-2
thunar-volman 0.3.80-4

If any other packages are important, let me know.
Small values of gtk-menu-popup-delay are making the penomenon probably; if the value is over 51 it almost doesn't happen. Right clicks in empty space are working normal.
While googling arround i also found some other people who seems to have the same issue:
