Thanks for your bug report. This bug has been reported to the developers of the software. You can track it and make comments here: http://bugzilla.gnome.org/show_bug.cgi?id=528882

This bug was fixed in the package libsoup2.4 - 2.23.91-0ubuntu1

---------------
libsoup2.4 (2.23.91-0ubuntu1) intrepid; urgency=low

  * New upstream version:
    - Fixed a crash in gvfs [#528882], though there is still an unknown bug
      there. As part of this fix, libsoup will now return an error if you try
      to do an operation on a non-HTTP URI. (lp: #216763)
      (Previously it was just treating any URI scheme except "https" as HTTP.)
    - Added soup_date_to_timeval() for gvfs.
  * debian/rules:
    - updated shlibs version

upstream bug comment

"This crash can only happen if something is trying to use libsoup to request a
URI that (a) has no hostname, and (b) is not http or https.

"???"

I've fixed libsoup to be pickier about the URIs it accepts. But this might just
push the crash to somewhere else in gvfsd-http. (Previously
soup_message_new_with_uri() would never fail, even if you passed a completely
bogus URI. Now it can return NULL.)

Another possibility is that it's the webdav server's fault, because it's
returning a totally broken redirect like:

    HTTP/1.1 301 Moved Permanently
    Location: C:\Documents and Settings\blah\blah

Previously, that would have triggered this crash. Now it will just cause the
message to finish with status SOUP_STATUS_MALFORMED.

Reassigning back to gvfs and NEEDINFO'ing, since there's still going to be
*something* wrong when the reporter tries the new libsoup."

could you try using the new version?

Now it works... bug can be closed... Thanks..

Closing the wrong gvfs task.
