            Bug ID: 469904
           Summary: Task manager freezes while evolution is sending an
                    email
    Classification: I don't know
           Product: kde
           Version: unspecified

SUMMARY
The (icons-only) task manager oftentimes hangs for a while when evolution is
sending an email. It doesn't happen every single time, and doesn't happen on a
fresh session start. I'm not sure what entirely triggers it, but after a while
of using the computer, every email sent through evolution hangs the task
manager.

STEPS TO REPRODUCE
1. Use the computer normally for many hours.
2. Launch evolution (GTK email client).
3. Add your user email, write an email to some other address, and send it.
Optionally, configure evolution to hold the email in an outbox for a while and
wait for the exact moment at which it is sent.

OBSERVED RESULT
The task manager hangs for 1-2 seconds. Clicking icons on it during this time
period doesn't trigger any action until the freeze is over, nor does
right-clicking the icons, whereas switching windows with alt+tab works
instantly. Other KDE apps like Kate do not suffer from any issues while this is
happening. If evolution is configured to send the emails instantly and one
groups windows of apps in the task manager, it will also cause a visual glitch
as described in bug 445539.

EXPECTED RESULT
The task manager's inner workings should not depend on what an email client is
doing.
