Nyxt does not accept URLs from system

[brosasaki]

Describe the bug
On Guix, clicking on a link in a different software while Nyxt is running will attempt to open the link in the running Nyxt, but will not succeed. Instead, an error message appears in the status buffer:
(UNSIGNED-BYTE 8) is not a velid :ELEMENT-TYPE for MAKE-STRING

Precise recipe to reproduce the issue
Enter echo https://gnu.org in any software the linkifies URLs (terminals, IM, emacs, etc.) and attempt to follow the link. Observe the error in the message bar.

@brosasaki thanks for the report.

The issue is similar to #3388.

I've added a patched Guix definition on my own channel - https://github.com/aadcg/aadcg-guix-channel.

I'll send the patch upstream but it may be take time and it's not guaranteed that it will be accepted.
