After installing fonts manually (not from an ebuild), the new fonts did not have correct permissions (only chmod 600.) I loaded a website that required the font in question, and firefox segfaulted. Reproducible: Always Steps to Reproduce: 1. Install a new font, chmod to 600 2. Start firefox 3. Load a webpage that requires the new font Actual Results: Firefox segfaulted. Error message varies. Expected Results: Either 1) Fallback to a known system font; 2) A warning indicating there's a font problem; or 3) Both 1 and 2.

I did forget to mention that running: $ chmod -R 644 /usr/share/fonts/* $ fc-cache -fv fixes it.
Not a fonts bug.
And not a Gentoo-specific bug at all, for that matter. Please report such things upstream - https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&format=guided
jakub, please leave bugs alone after they've been assigned.
*** Bug 187634 has been marked as a duplicate of this bug. ***
this might actually be the cause of several bugs we have open. i'll look into adding some checks to be sure all the fonts we install have the correct permissions. i'm not sure what we can do about user-installed fonts though. maybe i can make a case to fontconfig upstream to filter out fonts that aren't world readable.
Please do so. As I said in my other bug, I never did install any fonts manually - the error crept in elsewhere. I only wish at the time I had a way to figure out quickly which fonts were unreadable - too late now.
In a thread on the forums someone had this issue and konqueror was also affected; in that case media-fonts/arphicfonts is one of the packages that had incorrect permissions. There could be more than one package at fault though. m.nawaz: did you have arphicfonts installed? I don't, maybe I'll try emerging them right now.
OK, I tried media-fonts/arphicfonts-0.1.20060928 and the permissions are OK.
font.eclass now forces 0644 on all installed font files. thanks.

Portage uses "#new" suffixes when copying files to the system, and then renames them to their final filenames. This code was executing while another font was in the process of being copied to the system. Font packages should just ensure that they install files with correct permissions to begin with, and all except media-fonts/x11fonts-jmk already use 0644 permissions. media-fonts/x11fonts-jmk used 0444 (which was probably fine) until the previous commit which changes its installed files to 0644.

I want to remove that to avoid the race. This is the only package that installs fonts with permissions other than 0644, so override that in src_install(). The claim in font.eclass is that fontconfig segfaults if fonts are unreadable, but that claim dates to 2007 (bug #187774). Additionally, 0444 is readable, but who knows. Let's just keep things working how they have been since 2007.
