I believe something has changed in guix that breaks my package definition
of vscodium.

I had this package running for 6 months, and now it no longer works:
https://github.com/pink-gorilla/gorilla-guix-chan/blob/master/BAD/vscode.scm

I get this error:
gorilla/packages/vscode.scm:131:22: In procedure inputs:
 error: gdk-pixbuf+svg: unbound variable

Any ideas?
