Hello.
This is so far inside fontconfig and the theme engine that you use, so I
suspect nothing Emacs does can help. It seem to crash on
/usr/X11R6/lib/X11/fonts/misc/cu12.pcf.gz, have you tried to remove that file?
It may be a bad font (I don't know what cu12.pcf is, Courier 12?).
An idea why Emacs crashes and no other may be that Emacs uses only non-AA
fonts, whereas Firefox and other uses AA fonts mostly. But it is hard to tell.
If removing that file doesn't help, you could try to switch to a more basic
theme.
But all this is just shots in the dark, I'm afraid.
