The spanish dictionary is quite old (at least seven years). I made a new ebuild of the last version. Seems to work. Reproducible: Always
Created attachment 156043 [details] ebuild the ebuild
Thank you for report. Fixed in the tree. BTW, next time, please, attach diff of ebuild against latest version in the tree, instead of full ebuild. If diff size is zero you can just tell that simple copy is enough. Fixed.
