            Bug ID: 90503
           Summary: webdav: copying big files makes the session unusable
           Product: Spice
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: spice-gtk
          Assignee: spice-bugs at lists.freedesktop.org
          Reporter: me at victortoso.com

With patches from:
http://lists.freedesktop.org/archives/spice-devel/2015-May/019796.html

While copying big files from guest to client by putting those files in the
shared folder, the sessions freezes.
channel-webdav and spicevmc have a heavy workload repeating the following debug
over and over again. (I've included a debug on phodav to check the amount of
data requested each time, which is 8192 bytes).
The sessions is normal once the file has been copied.

Client and Guest: f22
Using spicy with latests spice-gtk git with above patches applied.
