Cannot convert string ... to type FontStruct

[Micha Feigin <michf@math.tau.ac.il>]

I get n error with several programs under linux (mostly xemacs21
recently) sayying that it can't convert string to type fontstruct. for
example:
Warning: Cannot convert string "-ttf-web hebrew
monospace-medium-r-normal-regular-*-160-75-75-m-*-iso8859-1" to type
FontStruct
Warning: Cannot convert string
"-ttf-globes-medium-r-normal-normal-*-160-75-75-p-*-iso8859-1" to type
FontStruct
xemacs will then start with a dfault font, which is very anoying (if it
helps, these fonts don't appear in the font list under xemacs, and they
are hebrew fonts).
I am using xemacs21.
