Description Aurélien Oudelet (auroud85_fr) 2020-08-04 16:43:53 UTC

SUMMARY
Opening application pinned as desktop graphical component leads to failing cgroup creation.

Launching whatever application pinned from a Plasma Panel results of following error:

plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-firefox (1)-fe5379b798a3465a9edd978a96bdf64c.scope"
plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-org.kde.dolphin (1)-ecac586e193d4319a28402bd0140f494.scope"
plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-systemsettings (1)-07939f87e1c24783ba4c0a4dff48361b.scope"

There is a typo error: a space after application name and this: (1) or (2).

Applications launched from Kicker are not affected.
Applications launched from pinned shortcut in Task Manager are not affected.

This is on 5.19.4 Plasma on current Mageia Cauldron.

STEPS TO REPRODUCE
1. Pin an application on panel with right click menu (Add to panel (graphical component))
2. Click on application icon like firefox, dolphin, systemsettings
3. See in journal error.

Comment 1 Aurélien Oudelet (auroud85_fr) 2020-08-04 16:49:54 UTC

Misbehaviour :

plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-firefox (1)-fe5379b798a3465a9edd978a96bdf64c.scope"
plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-org.kde.dolphin (1)-ecac586e193d4319a28402bd0140f494.scope"
plasmashell[4397]: kf5.kio.gui: Failed to register new cgroup: "apps-systemsettings (1)-07939f87e1c24783ba4c0a4dff48361b.scope"


Expected behaviour:

systemd[4209]: Started apps-org.kde.dragonplayer-5a0d91ee62584fd2967953621e529d72.scope.

systemd[4209]: Started apps-systemsettings-adefc010cdc74366a382489c61d4e79d.scope.

No space, no parenthesis on application name scope.

Comment 2 Aurélien Oudelet (auroud85_fr) 2020-08-04 19:53:48 UTC

After further analyze,

There is some desktop files in /$home/.local/share/plasma_icons

Why there is .desktop files here when there is no icons in Plasma's Panel ?

Deleting theses files, and pinning to Panel after some apps, there is no longer bug.

BUT: if I add as duplicate an app, the .desktop file has a space and parenthesis in filename, so the bug is reproduced:

plasmashell[4378]: kf5.kio.gui: Failed to register new cgroup: "apps-firefox (1)-fe5379b46df4469edd978a96bdg58v.scope"

Thanks for noticing. 
There is new escaping on review which hopefully should fix this issue.
