Hey are you able to confirm how both programs were installed, and if possible the absolute path to their desktop files please?

The opening process works by finding the desktop file and passing that to gtk-launch. There have been some recent changes to the code that finds the file so that might be a culprit.

Thunar and the bulk renamer are both called with thunar, so their paths are the same. Thunar was installed the usual way and you are free to reproduce my setup in NixOS.

$ whereis thunar
thunar: /nix/store/0rjs5mmfgzkvbarc5q4rpcn4488na206-system-path/bin/thunar

I also encountered issues with org.qutebrowser.qutebrowser opening zathura, ~~although surprisingly it works as expected now.~~ Looks like it doesn't work anymore.

qutebrowser also works, however it opens a separate icon (or uses org.qutebrowser.qutebrowser) instead of using the existing one.

I feel like this is related to the change used to fix github.com/nwg-piotr/nwg-dock-hyprland@5128931d1b, although I haven't digged in ./src/modules/launcher yet.

Yeah but what are the desktop file locations

Looks like home manager packages are in /etc/profiles/per-user/user/share/applications and system packages are in /run/current-system/sw/share/applications/. Both are in XDG_DATA_DIRS.

Thunar has different .desktop files for the bulk renamer and the usual file browser.

/run/current-system/sw/share/applications/thunar.desktop
/run/current-system/sw/share/applications/thunar-bulk-rename.desktop

/run/current-system/sw/share/applications/thunar.desktop

/run/current-system/sw/share/applications/thunar-bulk-rename.desktop

So I think I found it, in this code it's checking if any field "contains" it, so obviously it's going to be positive for thunar-bulk-renaner, I mean it includes thunar. But I'm not sure idk much about this code.

Ah yeah I think you're correct. The fix should just be to do a first pass that checks for an exact match, then do the contains in a second pass

Turns out it was actually incorrectly matching on the file name before reading any of the desktop files.

I've tested the above with thunar and thunar-bulk-rename and both now seem to be working reliably. It also shimmies the logic around a bit to try and prevent the same thing happening in other places.

If you're able to, could you give it ago yourself and let me know if it does the trick or you encounter any other false matches please?
