Serious bug: pcmanfm-ssh-leafpad [howto diagnose]

[rv riveravaldez <riveravaldezmail@gmail.com>]

Hi, I've found this bug consistently on debian testing (updated):

Steps to reproduce:
>From the address bar of pcmanfm, type:
ssh://user@ip
Write password, Enter.
Navigate to the remote machine user folder.
Open, edit and save a plain text file with leafpad.
The file gets blanked (no content at all).

Mounting the remote machine with sshfs and doing the next steps
identically works fine.

Packages:
leafpad     0.8.18.1-5
pcmanfm  1.3.0-1
ssh            1:7.7p1-2

Any recomendations on how to diagnose and report this bug?

Thanks a lot.
