Bug ID: 404542
Summary: Gwenview crashes after a few minutes of 180% CPU on
large directory of 12000 images
Product: gwenview
Version: 18.12.2
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: jpha...@gmail.com
Target Milestone: ---
SUMMARY
Gwenview crashes on a very large directory in Browse mode. The directory has
12111 images and 247 videos, totaling 36.2 Gb. Invoking Gwenview in View mode
works OK, consuming a lot (>80%) CPU, but still responds. Switching to Browse
mode instantly freezes the machine (unresponsive cursor response to mouse
moves, 180% CPU) which crashes after a couple of minutes. The behaviour is
repeatable.
System info:...
KDE Neon 5.14 running on Zotac E1750 with 4x core i7 CPU @ 3.2GHz, 16G RAM, 2Tb
SSD.

STEPS TO REPRODUCE
1. Use Dolphin to browse to the directory and select any image for open in
Gwenview
2. Gwenview works OK in View mode, able to switch between images and scroll the
thumbnail bar.
3. Switch to Browse mode

Gwenview freezes the entire machine, and crashes after a couple of minutes of
180% CPU use, according to 'top'. Mouse cursor doesn't resppnd to mouse
movement until after Gwenview crashes, when the system returns to normal.
EXPECTED RESULT
Normal browse behavior.
