PCManFM 1.2.0 / LXDE on ArchLinux 3.13.5-1 i686 GNU/Linux + 3.13.6-1 x86_64 + 188.8.131.52-2 armv7l.
Mounting sftp-server found under menu-item:Goto->Network ends up in endless login-loop because of auto added ':22' ssh-port specification.
Using avahi+nss-mdns for name resolution within my network the clients appear in PCManFM under menu item: Goto->Network with their hostname.
If you klick on one of the clients found, a sftp-link is created in the address bar like: 'sftp://servername.local:22/' and the login dialogue appears asking for username and password to log in. The ':22' seems to stand for the ssh port.
When typing the requested the computer hangs for ca. 10 seconds using 100% of one cpu-core and the login dialogue appears again.
This repeats forever until you cancel the password prompt and than the error message appears:
'The given location is not mounted'- while in the left column under 'locations' the server appears as mounted.
By clicking on the generated link on the left for the mounted share the address changes to one without the ':22' and you can access the files on the server without logging in again.
