Bug ID: 357791
Summary: Backtrace from MuonApplicationNotifier.so
Product: plasmashell
Version: 5.5.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: vishal...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.3)
Qt Version: 5.5.1
Operating System: Linux 4.3.0-5-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)
-- Information about the crash:
- What I was doing when the application crashed:
I believe whenever I run "sudo apt-get update" in konsole it triggers the crash
handler window popup. I am running Kubuntu 16.04 current (pre-alpha) with the
Kubuntu Xenial Landing PPA enabled for Plasma 5.5.3 and friends.
One of the lines in the backtrace is:
#8 0x00007fa63428e4a9 in ?? () from
/usr/lib/x86_64-linux-gnu/qt5/plugins/discover-notifier/MuonApplicationNotifier.so
When I went to install the debug symbols via the crash handler window it
messaged that "Symbols not available for MuonApplicationNotifier.so" but it did
install symbols for qt5base and plasma-desktop FYI.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
