   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Downgrading all those packages to 5.15.8+gfsg-3

   * What was the outcome of this action?

krunner alt-F2 shortcut worked again

   * What outcome did you expect instead?

Hello,

Arthur Marsh, le mar. 11 avril 2023 00:43:16 +0930, a ecrit:

I cannot reproduce the issue.  What I did was:

- install bookworm with the KDE desktop task
- upgrade libqt5core5a to 5.15.8+dfsg-4, that upgraded all other
  libraries from qt5base.
- rebooted
- logged into the KDE session
- pressed alt-f2, and krunner showed up.

I tried both with Xorg and wayland, in both cases it worked.

Is there something specific in your desktop environment, compared to
that situation?

The change included in 5.15.8+dfsg-4 is really not related to shortcuts
at all so this issue is very surprising.

Samuel

I confirm this problem, it should be in one of the following packages

Could you re-run with libdbus-1-3-dbgsym and libqt5dbus5-dbgsym
installed?

Samuel

I can install only  libdbus-1-3-dbgsym  (because found only
libqt5dbus5-dbgsym_5.15.8+dfsg-3_amd64.deb)

Below is the test with that package installed.

However, I can't do other tests, since I start restoring the PC to
yesterday, when everything worked.

Note that even the lock screen, after a few minutes of inactivity,
displays a never seen screen, which I inserted attached, I don't know if
it's a related problem.

Hello,

Thanks for the backtrace, I believe I understand what is happening.  I
came up with another solution that should be way safer.

Thanks,
Samuel

Hi Samuel,
after update to version 5.15.8+DFSG-6 krunner does not respond to Alt-F2.

Compared to before, the program is active in memory without errors.

The program runs but does not show activities.
