           Summary: KMail gets extremely slow (almost stops) when composing
                    a new message
           Product: kmail
           Version: 1.9.5
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: dusa.adrian gmail com


Version:           1.9.5 (using KDE 3.5.5, Kubuntu (edgy) 4:3.5.5-0ubuntu3.1)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-10-generic

This behaviour started in the last version of Kubuntu (Dapper) and I thought maybe there's something wrong with my system. I even changed my machine (now having a Core2Duo processor) and KMail still shows this.
The Compose window behaves very very slow; I type entire sequences of words and they get on the screen one letter at a time at a rate of one letter per second.
The System Load shows a dramatic increase in processor usage, only for composing new messages.

Other programs (even a word processor) behave as usual, but switching to the Compose window almost freezes it.

I hope I was explicit enough,
Adrian
