OBSERVED RESULT
[Peter ~]$ krusader
kf.i18n: KLocalizedString: Using an empty domain, fix the code.
msgid: "No jobs" msgid_plural: "" msgctxt: ""
10:48:40.951-warning kf.i18n unknown@0 # Trying to convert empty KLocalizedString to QString.
10:52:17.845-warning default unknown@0 # Cannot initialize model with data QJsonObject(). missing: QJsonValue(string, "urls")
10:52:36.612-warning qt.qpa.wayland unknown@0 # setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x56278d2e1500) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x56278d61d510) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents


EXPECTED RESULT
No error or warning messages

ADDITIONAL INFORMATION
I labeled this as "Minor" because it didn't seem to impact the actual system usage/output/etc, but
it does seem (to me) that testing should be done with /dev/err captured and reviewed.
