inFlatpakBackend::addAppFromFlatpakRef()
Classification: Applications
Product: Discover
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Keywords: qt6
Severity: normal
Priority: NOR
Component: Flatpak Backend
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
CC: aleix...@kde.org, jgrul...@redhat.com,
trav...@redhat.com
Target Milestone: ---
Did not see this in Plasma 5; seems to be a Plasma 6 regression.
Tested with

in Discover.
