Bug ID: 511305
Summary: Regression: folder thumbnails are generated despite
the option being deactivated in settings in dolphin
Classification: Frameworks and Libraries
Product: frameworks-kio
Version First 6.19.0
Reported In:
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
Dolphin generates thumbnails for folders when folder thumbnails area
deactivated and previews are enabled. The issue seems to lie in KIO or the
plugin itself.
STEPS TO REPRODUCE
1. Disable all thumbnails in Settings=>Interface=>Previews
2. View Settings in Compact mode with Previews enabled
OBSERVED RESULT
Folder thumbnails being created in .cache/thumbnails/
EXPECTED RESULT
No thumbnails being created.
SOFTWARE/OS VERSIONS
Operating System: Gentoo Linux 2.18
KDE Plasma Version: 6.5.0
KDE Frameworks Version: 6.19.0
Qt Version: 6.9.3
ADDITIONAL INFORMATION
This is a regression, I can't really pinpoint the exact version but thumbnails
were not created before I last updated(~last 2 months).
I did a bit of debugging, as far as I could:
-Dolphin calls filePreview with an empty(not nullptr) enabledPLugins.
-FilePreviewJob is called with an empty mimeMap
-The thumbnail is generated in slotStatFile
-m_plugin is never initialized and is the default one(I'm not sure this is
expected, it seems weird to me)
-KIO::TransferJob "thumbnail" schema is called with this(
https://github.com/KDE/kio/blob/master/src/gui/filepreviewjob.cpp#L594 ):
kf.kio.gui: mimeType: "inode/directory"
kf.kio.gui: width "0"
kf.kio.gui: height "0"
kf.kio.gui: plugin ""
kf.kio.gui: enabledPlugins ""
And it ends up generating a thumbnail.
