Description Joe Christy 2015-11-20 01:49:52 UTC

Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

trying to file a bug report using drkonqui to report a bug where plasmashell crashed while I was closing a konsole window immediately after logging in. The window had been restored after plasmashell crashed the last time I logged out in order to log in with freshly updated qt5 and kf5 libs.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Christoph Feck 2015-11-20 12:59:24 UTC

Already reported as bug 355621.

Comment 2 Joe Christy 2015-11-21 02:59:25 UTC

Please note that this was a second crash, after I had re-started plasmashell. FWIW this backtrace begins in thread 10 and 355621 starts in thread 11, and that the threads are in different places in memory.
Also note that bugs 355621 and 355622 happened with qt-5.5.1, while bug 355524 was with qt-5.5.0. After bug 355524, I googled and discovered that qt-5.5.1 was in Fedora updates-testing.
