           Summary: message disposition notification makes X server freeze
           Product: kmail
           Version: 1.9.5
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: hatto salesianer de


Version:           1.9.5 (using KDE KDE 3.5.5)
Installed from:    SuSE RPMs
OS:                Linux

To reproduce this bug:
* configure kmail to ask you in case of a Message Disposition Notification (MDN) request
* configure it to mark displayed messages as read after being displayed 3 seconds
* right-click in the message list on a message which contains a MDN request and has not been displayed before.

At first the context menu will open, after 3 seconds the popup window appears (I suppose that the english version will show the three options "send", "ignore", "deny") - and now the X server is litterally unusable: I can just move the mouse, but neither mouse clicks nor pressed keys show any effect. Not even Alt-Ctrl-Esc (to kill kmail) works; I am just able to kill the X-Server by pressing Alt-Ctrl-Back or to switch to a console (e.g. by Alt-Ctrl-2) in order to kill kmail from there. - At first I thought this bug to be similar to bug 98390, but situation and effect are different.

More than once it happened to me to leave all marks of my mails which is a severe denial of service for my work ...

I have experienced the the bug on a SuSE 10.1 with kmail 1.9.1 (KDE 3.5.1) and confirmed it on a SuSE 10.2 with kmail 1.9.5 (KDE 3.5.5). As a workaround one may configure kmail to mark mails as read without any delay (or to ignore MDNs).
