It's even worse then I reported above:

    mfabian at magellan:~$ xfd -fa "Nimbus Sans L"
    mfabian at magellan:~$

works.

    mfabian at magellan:~$ fc-match "Nimbus Sans L"
    n019003l.pfb: "Nimbus Sans L" "Regular"
    mfabian at magellan:~$

works. Now delete all global caches:

    mfabian at magellan:~$ sudo rm  /var/cache/fontconfig/*
    mfabian at magellan:~$

call fc-match again:

    mfabian at magellan:~$ fc-match "Nimbus Sans L"
    n019003l.pfb: "Nimbus Sans L" "Regular"
    mfabian at magellan:~$

.fonts.cache-2 has been created but it is weird:

    mfabian at magellan:~$ fc-cat .fonts.cache-2
    fc-cat: printing global cache contents for dir /home/mfabian/.fonts/kde-override
    mfabian at magellan:~$

and "xfd -fa" crashes now for all fonts:

    mfabian at magellan:~$ xfd -fa "Nimbus Sans L"
    Warning: Cannot convert string "Nimbus Sans L" to type XftFont
    セグメンテーション違反です (core dumped)
