Description Michael Hamilton 2020-01-25 09:02:32 UTC 
SUMMARY
Konsole with multiple tabs pops up an N open terminals warning on logout or shutdown.

STEPS TO REPRODUCE
1. Start a konsole and create more than one terminal/tab.
2. Logout or shutdown

OBSERVED RESULT
Konsole raises a popup with "There are N open terminals in this window. Do you still want to quit?"  It is impossible to respond sensibly because it is too late in the logout/shutdown sequence of activities.

EXPECTED RESULT
Previous behavior did not bring up any dialog which seems to make sense given there is no way to respond sensibly.

ADDITIONAL INFORMATION
Seems similar to old Bug 127194 but it only just started happening this week. Does not happen if there is only one tab open.
Comment 1 Wolfgang Bauer 2020-01-25 13:31:54 UTC 
That's not a bug in konsole though, IMHO.

IIRC, it started with the upgrade to Qt 5.14.0, and also affects other applications like Konqueror.
Comment 2 Wolfgang Bauer 2020-03-17 08:02:30 UTC 
It's caused by this change in Qt 5.14:
https://code.qt.io/cgit/qt/qtbase.git/commit?h=5.14&id=1b6db1849477be30ef0ca52c288d358b911ea1e4
(I built and installed Qt 5.14.1 with this change reverted, and the problem was gone)

What happens is that KMainWindow::tryClose() is called twice on logout now.
The first time qApp->isSavingSession() is true (and so konsole doesn't show the warning dialog), but the second time qApp->isSavingSession() is false (this didn't happen earlier, it causes the dialog to be shown now, but doesn't block the logout).

I suppose kxmlgui would need to be adjusted to that Qt change...

I mean KMainWindow::queryClose()...

Comment 5 Allan Sandfeld 2020-08-02 08:54:35 UTC 
So it is a change in what plasma does when logging out?

Ah right, read the comments again. So a change in how Qt closes applications.

Should be fixed by https://phabricator.kde.org/D29873
