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".
