Bug ID: 501398
Summary: kde-open5 improperly parses URL-encoded spaces in
obsidian:// and other custom URI schemes
Classification: Frameworks and Libraries
Product: frameworks-kio
Version: 6.11.0
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kio-bugs-n...@kde.org
Reporter: k...@klub100.beer
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
kde-open5 incorrectly processes obsidian:// URLs (and potentially other custom
URI schemes) by stripping or incorrectly parsing %20 (space encoding) and
possibly other special characters.
This results in applications failing to open the correct resource when xdg-open
is used within a KDE environment.
The issue does not occur when using gio open, indicating that the bug is
KDE-specific.
STEPS TO REPRODUCE
1. Ensure that obsidian:// is registered as a valid x-scheme-handler (e.g., via
Flatpak:
/var/lib/flatpak/exports/share/applications/md.obsidian.Obsidian.desktop).
2. run xdg-open "obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
OBSERVED RESULT
Instead of "Shopping List", kde-open5 passes "Shopping" as the file parameter.
This causes Obsidian to display an error: "Note 'Shopping' not found".
Debugging shows that kde-open5 truncates everything after the first space.
EXPECTED RESULT
Obsidian opens the correct note named "Shopping List" inside the vault
"obsidian-recipes".
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed
KDE Plasma Version: 6
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
ADDITIONAL INFORMATION
Setting XDG_CURRENT_DESKTOP=GNOME makes xdg-open work correctly by using gio
open.
This works as expected (bypassing KDE utilities):
gio open "obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
(Obsidian correctly opens Shopping List.)
This fails (when KDE takes over URL handling):
xdg-open "obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
(Results in Obsidian searching for Shopping instead of Shopping List.)
xdg-open Debug Output (showing KDE is involved):
XDG_UTILS_DEBUG_LEVEL=2 xdg-open
"obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
Selected DE kde
Received callback URL obsidian://open?vault=obsidian-recipes&file=Shopping
(Note how the received callback URL has stripped everything after the first
space!)
Strace output confirming kde-open5 is used:
strace -f -e execve xdg-open
"obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
execve("/usr/bin/xdg-open", ["xdg-open",
"obsidian://open?vault=obsidian-r"...], ...)
execve("/usr/bin/kde-open5", ["kde-open5",
"obsidian://open?vault=obsidian-r"...], ...)
(kde-open5 is modifying the URL before passing it forward.)
Possible Cause:
kde-open5 might be incorrectly splitting the URL on spaces instead of properly
handling URL encoding.
gio open does not have this issue, indicating the problem is KDE-specific.
Impact:
Affects any application relying on URL schemes (obsidian://, potentially
vscode://, tg://, etc.).
Affects all KDE users relying on xdg-open to launch URL handlers.
Forces KDE users to set XDG_CURRENT_DESKTOP=GNOME as a workaround.
Suggested Fix:
kde-open5 should respect encoded URLs (%20 should not be removed).
The full URL should be passed to applications unmodified.
Workarounds:
gio open "obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
XDG_CURRENT_DESKTOP=GNOME xdg-open
"obsidian://open?vault=obsidian-recipes&file=Shopping%20List"
Related Issues & Discussions:
Flatpak .desktop file for Obsidian is correctly set up (Exec=/usr/bin/flatpak
run ...).
Bug only happens in KDE, not GNOME/Xfce (which use gio open).
