2 messages are printed before the seg fault:
$ xsmc
Unable to load font
Unable to load font
Segmentation fault (core dumped)

The xsmc application expects to find 2 fonts which match the patterns:
"*-helvetica-medium-r-normal--12*"
"*helvetica*6*"

The helvetica fonts are not present by default in Ubuntu 12.10.

The attached patch tries additional font patterns, if helvetica is not found:
$ ./xsmc
Unable to load font: *-helvetica-medium-r-normal--12*
Using font: *-fixed-medium-*--12*
Unable to load font: *-helvetica-*--6*
Using font: *-fixed-medium-*--6*

The messages show the font name patterns, the application will return 1 if no fonts are found, Makefile has been modifed to use CFLAGS.

I exchanged email with the author of xsmc Lapo IK5NAX, who said "Really xsmc has been stopped several years ago, when I decided to rewrite it using gtk, you shuold find gsmc that make everithing xsmc do with someting more and e little better graphics..."

I find this is true, i.e. gsmc is already available as an Ubuntu package and appears to work correctly.

Still broken in 14.04

Steve,

It has been removed from Debian and the removal should filter down to
Ubuntu shortly.

See the threads titled:

This is a dead horse and is totally superseded by a newer package
upstream from the same author whom _RECOMMENDS_ switching up to "gsmc".

Yes, I just came here to recommend removing the package. I've tried gsmc and found it to be fully functional.

Thanks
