webdav via tramp failures and error

[ken]

Has anyone successfully used emacs to access a webdav server and edit 
documents on it?

Using <http://www.gnu.org/software/tramp/> as guidance, I tried opening 
an existing file for editing with "C-x C-f 
/dav:user@host:/var/www/html/webdave/index.html".  This "user" already 
has a password-protected account on this webdav server and has already 
logged into it with other apps (e.g., cadaver and the Gnome file 
manager) and created and edited files etc.

Moreover, tramp successfully connects to the same machine via ssh ("C-x 
C-f /ssh:user@host:/var/www/html/index.html") and allows the same user 
to edit documents outside of the webdav namespace.

So the failure isn't due to either networking or permissions.  Here's 
the emacs *Backtrace*:

What local system are you running? GNU/Linux? What is the gvfs version?

Best regards, Michael.

Michael,

Both the local and remote machines are running RH/Centos 5.8.

Where would I discover the gvfs version being used?

I'll add that, for now, the server is listening on port 80... something 
which I intend to change as the project moves forward.


Thanks,
ken

# yum list | grep -i gvfs

It doesn't look like there's anything available for 5.8, either in the 
official repositories or in the half dozen other repositories I'm 
subscribed to.  (This is one major reason my next OSs are coming from 
somewhere else.)

Compiling from sources is no problem.  I just found 
<http://ftp.gnome.org/mirror/gnome.org/sources/gvfs/0.99/>.  What's the 
lowest version number of gvfs that I can use?  (The higher the version 
level of an app, the more likely it is it'll require libraries not 
already installed, leading to dependency failures and that to an 
unending chain of required upgrades to satisfy all the additional 
dependencies... ad nauseum.)

Thanks again.

The Commentary section of tramp-gvfs.el says:

--8<---------------cut here---------------start------------->8---
;; Access functions for the GVFS daemon from Tramp.  Tested with GVFS

--8<---------------cut here---------------end--------------->8---

I believe there is an incompatibility with the recent GVFS 1.14.0, but
this I must recheck.
