Summary: kdeinit5 segmentation fault in XRenderHasDepths when
using dolphin to open a firefox directory
Product: frameworks-kinit
Version: 5.68.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: fa...@kde.org
Reporter: matthew.fagn...@utoronto.ca
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
I was using Plasma 5.18.4.1 on Wayland in the Fedora Rawhide live image
Fedora-KDE-Live-x86_64-Rawhide-20200414.n.0.iso which has KF 5.68.0, Qt 5.14.2.
I downloaded Firefox Nightly 77.0a1 (2020-4-18). I extracted Firefox using ark
19.12.3. I opened dolphin 19.12.3 on Wayland, and I selected the firefox
directory in dolphin. A segmentation fault in kdeinit5 in XRenderHasDepths at
Xrender.c:126 in libXrender-0.9.10-11.fc32.x86_64 was shown by dr. konqi. The
same crash was shown 4/4 times when I opened the firefox directory in dolphin.
The trace has some functions involving thumbnails so some thumbnails in the
firefox directory might be involved.
Application: kdeinit5 (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

STEPS TO REPRODUCE
1. Boot Fedora Rawhide KDE Plasma spin live image
Fedora-KDE-Live-x86_64-Rawhide-20200414.n.0.iso from
https://koji.fedoraproject.org/koji/buildinfo?buildID=1493256
2. sudo dnf upgrade --refresh (in konsole)
3. sudo dnf install kwin-wayland plasma-workspace-wayland
4. Start Plasma System Settings
5. Select Login Screen (SDDM) > Advanced
6. Set Automatically log in to off
7. Close Plasma System Settings
8. Log out of Plasma
9. Log in to Plasma on Wayland
10. download Firefox Nightly 77.0a1 (2020-4-18) from
https://www.mozilla.org/en-US/firefox/77.0a1/releasenotes/
11. Extract Firefox with ark
12. Start dolphin on Wayland
13. Open the firefox directory extracted with ark
OBSERVED RESULT
kdeinit5 segmentation fault in XRenderHasDepths when using dolphin to open a
firefox directory
EXPECTED RESULT
No crashes would happen.
