From "man fc-cache":

<quote>
fc-cache scans the font directories on the system and builds font information cache files for applications using fontconfig for their font handling.

If directory arguments are not given, fc-cache uses each directory in the current font configuration. Each directory is scanned for font files readable by FreeType. A cache is created which contains properties of each font and the associated filename. This cache is used to speed up application startup when using the fontconfig library.

Maybe there is a simple solution available.
