hey there,

so that very good friend of mine created a script called "somethin / something" it works fine and all (well, not judging the code here)

the export also works (except it doesn't)

and the import crashes

so the export process actually creates a reasonably good folder name for the script ("somethin -- something") but then it creates a subfolder called "somethin" and that subfolder contains the script "something.user.js" (.gm.json is at the same level as the subfolder )

and the import process crashes on import.js:81:31

Operating System: linux debian 12 stable
Firefox version: 128.8.0esr (64-bit) (from the debian package)
Greasemonkey version: 4.13

easy to reproduce:
1 - create a new user script called "somethin / something" and save
2 - export a backup of your scripts from greasemonkey
3 - import that backup you just created with greasemonkey -> the progress bar freezes

(i'm sorry for reporting this bug)
