strace and KIO debug output demonstrating that KIO launches Nautilus with the
kio-fuse path instead of the native trash:/ URI.
DESCRIPTION
When Nautilus is configured as the default file manager, opening the Trash via
KIO (for example using `kioclient exec trash:/` or by clicking the Plasma
desktop Trash icon) launches Nautilus with the kio-fuse mount path instead of
the original `trash:/` URI.
Nautilus supports the `trash:` URI natively, therefore the URI should not be
translated into a kio-fuse path.
Instead of opening the native Trash view, Nautilus is started with a path
similar to:
/run/user/1000/kio-fuse-XXXXXX/trash
STEPS TO REPRODUCE
1. Set Nautilus as the default file manager:
xdg-mime default org.gnome.Nautilus.desktop inode/directory
2. Execute:
kioclient exec trash:/
or click the Trash icon on the Plasma desktop.
3. Observe the location opened by Nautilus.
OBSERVED RESULT
KIO launches Nautilus with the kio-fuse mount path instead of preserving the
original URI.
KIO debug output shows:
kf.kio.gui: Launching processes via KProcessRunner::SystemdAsService
kf.kio.gui: Starting process:
QList("/usr/bin/nautilus",
"--new-window",
"/run/user/1000/kio-fuse-KiUDcT/trash")
The same behaviour occurs when clicking the Plasma desktop Trash icon.
EXPECTED RESULT
KIO should launch Nautilus using the original URI, for example:
nautilus --new-window trash:/
or otherwise preserve the original `trash:/` URI instead of translating it into
a kio-fuse filesystem path.
Since Nautilus already supports the `trash:` URI natively, no translation
through kio-fuse should be necessary.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.7.2
KDE Frameworks Version: 6.27.0
Qt Version: (please fill in from `kinfo`)
ADDITIONAL INFORMATION
The following commands open the correct native Trash view:
nautilus trash:/
gio open trash:/
However:
kioclient exec trash:/
always translates the URI into the kio-fuse path before launching Nautilus.
`strace` confirms that KIO launches:
/usr/bin/nautilus --new-window /run/user/1000/kio-fuse-KiUDcT/trash
instead of:
/usr/bin/nautilus --new-window trash:/
As a workaround, wrapping the Nautilus executable and translating the kio-fuse
path back to `trash:/` restores the expected behaviour.
There is also a recent KDE Discuss thread where another user appears to
encounter a similar `trash:/` to `kio-fuse` translation while investigating
unexpected Trash behaviour. Although the symptoms are different, it may
indicate that the same KIO URL translation or launching logic is involved:
https://discuss.kde.org/t/dolphin-opens-personal-folder-instead-of-trash/45119
This may be related to bug 457685, which was also caused by KIO unnecessarily
translating URLs for non-KDE applications through kio-fuse. Although the
trigger is different (trash:/ vs. local file paths), both issues appear to
involve the logic deciding whether a URI should be preserved or converted to a
filesystem path.
