https://bugs.kde.org/show_bug.cgi?id=331634 Bug ID: 331634 Summary: Plasma Desktop Crashes After Login Classification: Unclassified Product: plasma Version: 4.12.2 Platform: Mint (Ubuntu based) OS: Linux Status: UNCONFIRMED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: plasma-bugs@kde.org Reporter: admin@twprogrammers.com Application: plasma-desktop (4.12.2) KDE Platform Version: 4.12.2 Qt Version: 4.8.6 Operating System: Linux 3.11.0-12-generic x86_64 Distribution: Linux Mint 16 Petra -- Information about the crash: - What happened last session: I was having internet issues, so I dug around. *Modified /etc/network/interfaces *Modified /etc/resolv.conf *Ran "service wicd restart" *Ran "service networking restart" ---- Plasma Desktop Crashed here, but did not produce a "good" backtrace as the only thing it produced was "Segmentation Fault 11" or something like that. Just one line. And yes I have ALL debugging symbols for my installed packages installed. ---- *Pinged google.com *Ran "host google.com" *Ran "dig google.com" Internet was working now, but Plasma Desktop wasn't able to start as it was giving the exact same message as before everytime I tried to restart it. So I used tty1 logged in as root to restart KDM. - What I was doing when the application crashed: Logging in - Unusual behavior I noticed: An error popped up after logging in via KDM saying something about a file not existing. After clicking ok on that error box, it showed my KDM splash, and after that I got the Plasma Desktop Shell has crash dialog. However, as you can see, it produced a worthy enough backtrace to be sent in. - System: OS: Linux Mint Petra (16) KDE Edition Arch: amd64 Ram: 4GB Physical, 7.45GB Swap Processor: AMD Phenom 9750 Quad-Core 2.4GHz Storage: 160GB SATA HDD KDE: 4.12.2 (upgraded via Kubuntu PPA) The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
