Description

As of the most recent update, Plasma Workspace menus no longer pop up the expected menu. Instead, an error message pops up with the following content:

Error loading QML file: file:///usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/Kickoff.qml:31:1: plugin cannot be loaded for module "org.kde.plasma.private.kicker":
Cannot load library /usr/lib/qt/qml/org/kde/plasma/private/kicker/libkickerplugin.so: (/usr/lib/qt/qml/org/kde/plasma/private/kicker/libkickerplugin.so:
undefined symbol: _ZN9KFileItemC1ERK4QUrlNS_21MimeTypeDeterminationE)

A similar message is shown for any other application-menu I attempt to use - the Dashboard, Launcher and Menu options.

I have attempted removing and re-installing KDE Plasma and its dependencies, which has not fixed the issue.

Arch upstream does not appear to have this bug.

so far i have determined

  • both files named in the error message are in the 'plasma-desktop' package
  • both files named in the error message exist in the filesystem
  • the missing symbol does exist in the named .so
  • the 'plasma-desktop' package and all of its direct dependencies come from arch
  • the problem is not reproducible on an arch system

  • Status changed from unconfirmed to confirmed
  • Subject changed from KDE Plasma workspace menus no longer work. to KDE Plasma workspace kickoff menu no longer works

after downgrading 'plasma-desktop' to 5.15.5-1 (and all deps that it originally pulled in), the problem disappeared

[core]

one thing i noticed was that with the current packages there were no graphical icons on the desktop, but after downgrading they all appeared normally - so it does seem to be related to mimetypes

these are the packages that i downgraded to their 2019-05-30 state

Updated by bill-auger 10 days ago

after returning [core], [extra], and [community] to current, and enabling the [kde-unstable] repo, then upgrading 'plasma-desktop' and it's deps, the desktop was totally unusable

[kde-unstable]
Include = /etc/pacman.d/mirrorlist

after disabling the [kde-unstable] repo and bringing everything back to the current state, only a small number of packages needed to downgrade, and the original bug returned

I have, for now, downgraded plasma-desktop back to 5.15.5-1, in which this issue is not present. Its dependencies were initially also downgraded, but have been re-updated.

Issue seems to no longer be present as of version 5.16.1-2 of the plasma-desktop package. Kickoff menu, as well as other panel menus, function as they should.

  • Status changed from confirmed to invalid

working for me now too - there was probably a dependency that needed to catch up
