bug#30189: [PATCH] Re: bug#30189: Retux game halts after preloading levels (missing ucd.sqlite uniseg database)

[Ben Sturmfels]

Patch for python-uniseg attached that fixes bug#30189.

Sorry if this is a duplicate, but I can't seem my previous email in the
guix-patches archives. Maybe because I missed the [PATCH] in the subject?
