            Bug ID: 410859
           Summary: plasmashell hangs for multiple seconds while nmcli is
                    also slow to respond
           Product: plasma-nm
           Version: 5.15.5
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: applet
          Assignee: jgrul...@redhat.com
          Reporter: aspotas...@gmail.com
  Target Milestone: ---

SUMMARY
plasmashell hangs for multiple seconds while nmcli is also slow to respond.

STEPS TO REPRODUCE
1. Somehow get to a situation when "nmcli c" takes multiple seconds to return
results.
2. Click on the plasma-nm icon in Plasma system tray.

OBSERVED RESULT
The panel is only opened after several seconds, at the same time when "nmcli c"
un-hangs if run in parallel on command line. The whole Plasma panel is
unresponsive, IOW it's not only the plasma-nm applet which is affected by this
kind of freeze.

EXPECTED RESULT
Plasma shell should be responsive at any point in time. Plasma-nm should also
open its popup immediately when clicking on the tray icon, even if
networkmanager is slow to respond. The popup window should probably indicate if
it's currently showing outdated information, e.g. more than several seconds
old.
