           Summary: Kopete spinning/hang in MSN code
           Product: kopete
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kopete-bugs at kde.org
        ReportedBy: linuxhippy at gmail.com


Version:            (using KDE 4.4.0)
OS:                Linux
Installed from:    Fedora RPMs

Without any MSN specific activity kopete suddenly didn't react to user inputs
and consumed 100% cpu.

pstack showed it was spinning somewhere in MSN code, I also did a sysprof
profile for an in-depth analyzation.
