           Summary: Kmail/Kontact performance when loading many
                    attachments
           Product: kmail
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: andy at mopoke.co.uk


Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

When loading certain emails (notably ones which have a number of attachments),
KMail (and by extension, Kontact) grinds to a halt. The CPU usage of the
process goes up to 98 or 99%.

When doing an strace, I get pages and pages of output such as:
