Want to report a bug, don't know which package

[Janek Stolarek <jwstolarek@gmail.com>]

Hi all,

I recently updated from Bullseye to Bookworm and noticed that font hinting settings in 
`~/.config/fontconfig/fonts.conf` are ignored. This was not the case on Bullseye and I'd like to 
report this as a bug. When I run reportbug it asks for a package name, but I have no idea which 
package this bug should belong to. Help appreciated.
