Bug ID: 397144
Summary: Discover 5.13.4 freezes after searching for 'scan'
Product: Discover
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: yst...@posteo.net
Target Milestone: ---
--What I did when the freeze occured––
Opened Discover from Kickoff, immediately searched for 'scan' in the search
field. Discover froze after displaying the search results.
Reproducible always.
plasma-discover --version outputs 5.13.4.
