            Bug ID: 95416
           Summary: SIGSEGV - spice-server - on file transfer while
                    killing the agent
           Product: Spice
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: server
          Assignee: spice-bugs at lists.freedesktop.org
          Reporter: bugzilla at victortoso.com

Not 100% reproducible here. I had to kill the agent and start the file transfer
three or four times to make it crash.

Program received signal SIGSEGV, Segmentation fault.
