works: zathura file.pdf
doesn't work: xdg-open file.pdf

Both launch zathura since it's my default reader. In the xdg-open case,
clicking a link in a pdf seems to not do anything. If I launched with
zathura explicitly, it opens the link in my existing instance of
qutebrowser as I would expect.
No errors related to clicking the link seem to show up in a terminal.
When launched either way I do get a lot of errors saying
```
error: plugin: filetype already registered: application/pdf
```
and then similar ones for oxps, epub+zip, xml, etc. as well as a message
that libdjvu.so cannot be registered as a plugin. These seem like
non-fatal errors and are probably unrelated, but I thought I would
mention them anyway.

[Message part 1 (text/plain, inline)]

in my mimeapps.list file I have zathura set like this:
application/pdf=org.pwmt.zathura.desktop
application/octet-stream=org.pwmt.zathura.desktop;
application/pdf=org.pwmt.zathura-pdf-mupdf.desktop;

I noticed there are two other zathura.desktop files on my system.
~/.guix-profile/share/applications/org.pwmt.zathura.desktop
~/.guix-profile/share/applications/org.pwmt.zathura-djvu.desktop
~/.guix-profile/share/applications/org.pwmt.zathura-pdf-mupdf.desktop

Perhaps I'm using the wrong one here. I also noticed I have two
application/pdf lines, but the first one is from the Default
Applications section and the second is from Added Associations.

Deleting the first line then makes xdg-open use a browser to open the
pdf, so I don't think that's the right way to go.

I tried also copying the later application/pdf line and replacing the
first one in the file with it, so this way it's still in the file in
both sections. With this, the file opens in zathura again, but clicking
links still does nothing. I'm not sure of the significance of the
semicolon at the end. Some of my lines have it, and some don't.

I'll attach my mimeapps.list file in case it's helpful to look over in
its entirety. (file has been reverted to the state it was at the start
of troubleshooting since none of the changes so far fixed the issue)

Okay, disregard. It seems a double-click is required rather than a
single click, and it takes about 5 seconds for anything to happen. I was
possibly clicking a different number of times between tests. Maybe I was
more desperate when I launched with zathura explicitly. It seems to work
the same both ways now.
