Hi,
Remember this old thread? It's been a while, I've been running firebird
0.6.1, rock stable, since higher versions crash.
I just updated firefox again, to 0.8_4, to see if this has changed, and I
think I have pinned down what causes the error, although I still can't
understand why.
It is the bitmapped fonts from the XFree86-75dpi | 100dpi packages, that
firefox cannot stand. Removing those directories from the system's root
fonts.cache-1 file makes the problem go away.
Details:
Firefox >= 0.7 crashes often, and sometimes xemacs freezes as this happens.
I have a standard X setup (well right now the X server is 3.3.99 snap, but
it wasn't before, and this has nothing to do with it). I use xfs for
serving all fonts, but this seems also to be beside the point - AFAIKT,
firefox uses fontconfig/freetype2 and not X for font rendering, right?
Fresh FreeBSD 4 stable. Latest versions from the ports collection, tried
rebuilding and force install the X font packages from ports, didn't help.
When installing fontconfig, it runs fc-cache -f --system-only, and this
creates a /usr/X11R6/lib/fonts/fonts.cache-1. This file contains, among
others, the lines
"75dpi" 0 ".dir"
"100dpi" 0 ".dir"
Now, removing these two lines from /usr/X11R6/lib/fonts/fonts.cache-1 makes
firefox a nice boy, no more crashing.
This small html file crashes firefox for me. Truss(1) informs me that the
Times font is taken from the 100dpi folder.

Altering "Times" to something else, like "Verdana" helps, of course, since
Verdana corresponds to a scalable font file.
Any ideas about this? A workaround, using some simple fonts.conf magic, is
obvious, but why is this happening, and is it only me? I have the same
problem in two different locations, office and home. At the office, X11R6
is NFS-exported, and the problem happens to everybody.
mozilla 1.6 fetches the fonts the same way, according to truss, but does
not crash... fire(bird|fox) version 0.7 and up all show the same fault.
firebird <= 0.6.1 are OK.
