Bug ID: 466617
Summary: kdeconnectd crashes when attempting to pair a device
while playing MPRIS music without album art
Classification: Applications
Product: kdeconnect
Version: 22.12.2
Platform: Archlinux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: common
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
Application: kdeconnectd (22.12.2)
Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.10-273-tkg-pds x86_64
Windowing System: Wayland
Distribution: EndeavourOS
DrKonqi: 5.27.1 [KCrashBackend]
-- Information about the crash:
Sometimes when attempting to pair from my Fedora 36 laptop running GSConnect,
the KDE Connect daemon on the host computer will crash. I noticed a mention of
mpris in the crash log, and I was using an application that supports it on the
host computer (specifically Cantata); however, I was playing back a radio
stream without any album art.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault
