The issue has been going on for a while, but I don't think I ever
reported it. I have my xdg-open stuff configured properly and almost all
programs on my system can open links where relevant. However, Qt
programs like the couple I mentioned seem to not use my existing xdg
settings for some reason. Has anyone else experienced this? I am using
Sway, by the way.

I also have this issue in Quassel. Rather annoying but I assumed it was

just Qt weirdness.

I have recently installed both nheko and quaternion and links are

clickable there (and are opened in my browser)

I am using i3. Sorry I cannot test on Wayland.

I really don't understand what changed, maybe I just updated my

environment by logging out and then in again (aka: nheko and quaternion

was using /usr/bin/xdg-open installed by Debian), but now I also have

this problem with nheko and quaternion

In nheko I get:

Similar message in quaternion:

I don't have the referenced store item:

ls: cannot access '/gnu/store/bi4m86lripz4fhhi4c34ylg5ckxsrqzs-xdg-utils-1.1.3/': No such file or directory

AFAIU this is a bug.

Maybe adding xdg-utils to the inputs of nheko and quaternion solves this

issue?

Thanks! Gio'

Interesting. Does guix gc --references show this as a reference of

either? There have been instances of references being hidden from the

garbage collector by compression or overzealous (and pointless)

'optimisations'. It hardly ever happens in practice but it does.

If not, could you grep your ~/.cache and ~/.local directories for that

hash? Some programmes have a bug where they save absolute file names

instead of looking in $PATH every time. That should be fixed upstream.

How could either package refer to xdg-utils if it weren't already an

input? I don't see how.

Tobias,

first of all I have to add that on my laptop, with the very same

channels and manifests configuration, I'm not experiencing this issue.

Yesterday I did a garbage collection via "guix gc", could have been

I did a "find ~/.cache -type f -exec grep --color -nH --null -e

reference to that hash in this files:

Probably some qt related tool stored the (wrong/old) absolute path of

xdg-open and both nheko and quaternion on my desktop are using that

value when they try to open URLs... so yes, I'm almost sure the issue

is related to my environment/configuration.

...but what... where?!?

This seems likely to be the issue. I rebooted in the last week and I
just noticed that links in nheko are working again. That makes me wonder
if updating my packages without restarting my session/computer is what
breaks the links, and then rebooting maybe fixes the functionality again
if it re-saves an absolute file name to the new spot after a reboot.
I just tested quaternion and I can currently open a link from there as
well.

One of the nheko devs says nheko doesn't do this, but that it calls a Qt
function. So, this could be a wider Qt issue, or "Qt weirdness", as
raingloom said earlier.

I have the same issue with all of Qt applications that are using `QDesktopServices::openUrl(...)`. I developed some applications that are using this method of Qt. In all of them I get this error when I want to open links:

```

Launch failed (/gnu/store/bi4m86lripz4fhhi4c34ylg5ckxsrqzs-xdg-utils-1.1.3/bin/xdg-open ....)

```

The current `xdg-utils` path in my store is:

```

/gnu/store/0zdclmgw5gnpifwb7jyrmplrk13wp0yz-xdg-utils-1.1.3/

```

This is the references of my application by `guix gc`:

```

$ guix gc --references /gnu/store/dyrg1naixia5w4qg9d1mj8smi1lyww2n-px-software-0.3.3/

```

I think the wrong path will be set here:

https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/qt.scm#n442

I don't know why and where this wrong `xdg-utils` path come in.

I've observed the same behavior with Anki, a Qt application; when a link

is clicked, the following message is printed in the terminal (and the

link isn't opened, of course):

qt: Launch failed (/gnu/store/bi4m86lripz4fhhi4c34ylg5ckxsrqzs-xdg-utils-1.1.3/bin/xdg-open https://ankiweb.net/[...])

I only installed Anki a few hours ago, but did run 'guix gc' recently

(with a delete-generations argument of 1-3 months, IIRC).

ripgrep was unable find that hash mentioned under ~/.cache or ~/.local

(in ASCII/UTF-8 or UTF-16{LE,BE} encodings; UTF-32 appears to be

unsupported).

Thanks to Tobias Geerinckx-Rice for sharing some debugging suggestions.
