psvn with svn+ssh protocol working copy

[Seb]

Hi,

Although I can checkout, commit and do all operations I need from a
shell, I cannot update my working copy of a directory under SVN control
with svn+ssh in Emacs with psvn.  I get the message:

svn failed:
Network connection closed unexpectedly

in the minibuffer.  Checking the comments on psvn.el, I see that using
x11-ssh-askpass would help, so I installed Debian sid's ssh-askpass
package, and now I'm shown a graphical dialog to enter the passphrase.
This works fine, but requires typing the passphrase with every commit or
update.

The comment in psvn.el ($Id: psvn.el 35820 2009-02-11 21:35:14Z) from
GNU Emacs 23.1.50.1 (x86_64-pc-linux-gnu, GTK+ Version 2.18.3) of
2009-10-23 on elegiac, modified by Debian, reads:

,-----[ psvn.el (lines: 1283 - 1292) ]
|                     ;; Communicate with the subprocess via pipes rather

|                     ;; scheme is being used, SSH will not ask for a

|                     ;; to answer such prompts.  Instead, SSH will run
|                     ;; x11-ssh-askpass if possible.  If Emacs is being

|                     ;; then run ssh-add explicitly.

However, I do have ssh-agent running, and have also run ssh-add, but I'm
still being presented with the dialog.  Has somebody had to deal with
this?  Thanks in advance.


Cheers,
