Description Vincent LaConte 2020-01-26 16:22:29 UTC

Application: gwenview (19.12.1)

Qt Version: 5.12.4
Frameworks Version: 5.66.0
Operating System: Linux 5.4.10-rt5-xanmod x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
Viewing usually four to six photos at once using the View module (NOT full screen, not Browse); selecting some and deselecting others, moving some to the Trash. Eventually Gwenview always crashes during this activity, often within < 5 minutes.

- Custom settings of the application:
1) sometimes but not always I boot the Xanmod-rt (realtime) custom Kernel ,the latest version. Otherwise I use the latest stable release version currently 5.3 (ubuntu) or 5.4 (manjaro)
2) as hinted above, i use Ubuntu mainly, but also sometimes boot from another HDD partition containing Manjaro 18.1.5. I log in with the same home/user to both installations, which is nearly seamless while both are using KDE 5. The Gwenview crashes first started when booted into Manjaro. However, it is happening as much or more now back in Ubuntu.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault

gwenview (20.08.2) using Qt 5.14.2

This is an update to bug #416794 which I reported under 19.10. It's still an issue under 20.10, although possibly a bit less frequent. 

Notes -- Although I've stuck with the mainline (HWE) kernel, my DE has become a kludgy mongrel of KDE-Plasma and PopOS-Gnome, with Qt libraries unevenly installed. While I still wouldn't be surprised if this bug is a result of that, it has been consistent through multiple distro upgrades and desktop constellations for ~18 months.

gwenview (20.08.2) using Qt 5.14.2

- Followup to my own original bug report. I can't claim to decipher the backtrace , but I can see it's been trimmed to a single thread this time – not by me.

This is while running the System76 OEM custom kernel (5.8.0), which despite wanting Gnome not KDE, lately has been more stable WRT drivers than the generic distro release of the past few. In which HD Audio, BT and wifi drivers,  on top of the expected nVidia problems, all are subject to intermittent failure to load after kernel updates.

gwenview (20.08.2) using Qt 5.14.2

- What I was doing when the application crashed:

Same behavior as  before, slightly different system and backtrace, (if these additional crashes are helpful someone let me know otherwise I'll just be quiet now.
