xchat goes down at exactly the same point

Looks like some font problem to me. What locale is this in ? 
Do you have any strange fonts installed.

Comment 4 Ralf Ertzinger 2006-01-15 01:02:10 UTC
This is in en_US.UTF-8.
I have done some more digging on this and have come up with the following:

a) It has nothing do do with my user-font-config (I moved my locally installed
fonts and .fonts.conf aside and it still happens)

b) It has something to do with the "Fixed" font. I can persuade any gnome
program (including gnome-font-properties) which displays a font selection dialog
to crash by just clicking "Fixed" in the "Family" list.

c) 'fc-match "Fixed"' yields 'kaname-latin1.pcf.gz: "Fixed" "Regular"', which
seems to be owned by fonts-japanese-0.20050222-11.1. The files on the disk
verify against the RPM database.

d) removing fonts-japanese makes selecting "Fixed" safe again, and
sylpheed-claws does not crash any more. 'fc-match "Fixed"' now yields
'console9x15.pcf: "Fixed" "Regular"'. The font is ugly, btw :)

e) reinstall fonts-japanese, and everything goes south as soon as Fixed turns up.

Comment 5 Ralf Ertzinger 2006-01-18 11:54:37 UTC
I noticed yesterday that another font (from fonts-korean) showed the same
behaviour. I then hunted down all fontconfig cache files on the system
(fonts.cache-1, fonts.cache-2, /var/cache/fontconfig), deleted them and reran
fc-cache. Since then all fonts (including Fixed with fonts-japanese) seem to
work again.

Why does fc have to use different cache files for every other release?
