Bug ID: 369553
Summary: Plasma crashed when disabling WiFi in KDE connect
Product: plasmashell
Version: 5.7.5
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Application: plasmashell (5.7.5)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.4-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"
-- Information about the crash:
- What I was doing when the application crashed:
Disabling Wi-Fi in KDE Connect
- Unusual behavior I noticed:
Very slow wi-fi connection. The reason why i disabled wi-fi was very slow speed
(max 30kbps). When plasma restarted a I reenabled Wi-Fi, speed was back to
normal.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
