Bug ID: 372022
Summary: kmail2: message is displayed and blanked after short
delay. Mail actions then crash kmail2.
Product: kmail2
Version: 5.3.0
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: UI
Assignee: kdepim-b...@kde.org
Reporter: jan_br...@gmx.net
Target Milestone: ---
When selecting a mail in message view, the message is displayed and then
disappears after a variable delay. Changing to another mail and then back does
not triggering this behaviour. The disappearing message happens in the embedded
message view as well as in an extra window (after double clicking the message).
If the mail display is blank and I trigger any message related, e.g., reply,
forward, delete, kmail crashes. But if I redisplay the message and do the same
action while the display is intact, everything will work fine. Nonetheless,
this mail focuses on the disappearing of the displayed mail.
I see the following backtrace, which seems to lead into the depths of
QtWebEngine.
