Comment 5 for bug 1333354

I tried this in Ubuntu Studio 14.04. and Xubuntu 15.10. If I have both Thunar and PCManFM installed, and automounting enabled - I don't know, if there is difference, if it is enabled in only one or in both - mounting fails in the later session in 14.04. If only Thunar is installed, it succeeds to mount, but when I return to the first session, the password dialog is there for mounting. In 15.10 mounting seemed to work even if both Thunar and PCManFM are installed and set to automount.
