            Bug ID: 372864
           Summary: My best newbie guess: 85% operator error for this
                    repeating crash of non-yast net-mgr.
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: delintux at yandex.ru
  Target Milestone: ---

Application: kde5-nm-connection-editor (5.8.2)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.27-2-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- Custom settings of the application:
in attempts to (unnecessarily) force the 'OEM' net-config manager GUI (which
comes with 42.2 for dumb hicks like me) to connect both of my wlan to home
network, and my new ethernet connect simultaneously, when i thought I had
finally found 'the sweet spot' among the settings for each, therein, the field
where my three desired connections were listed began filling with 8 or more
instances of both my wlan connections, repeatedly, multiple instances of my
LAN, as well as every other SSID near me which was detected in scans I never
wanted but am not learned enough yet to prevent without disabling networking
alltogether...  then crashing as a result of buffer overflow, if you were
buying me a beer,  just to make a newb-guess.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Connection editor (kde5-nm-connection-editor), signal:
