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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
