User-Agent: Mozilla/5.0 (compatible; Konqueror/3.1; Linux) Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5a) Gecko/20030904 Mozilla Firebird/0.6.1 If truetype fonts that MozillaFirebird expects to use are not readable by the user, the browser will pop out of existence without any info to a terminal or gui. This baffled users on Gentoo forums. Others observed this behavior in Thunderbird as well, but I have not confirmed this. The bug is that there is no information that would indicate the problem to the user to stderr, X or otherwise. Reproducible: Always Steps to Reproduce: 1.Import a font from a Windows partition or chmod a ttf font as 400 2.Run fc-cache -f so to be sure the font is used or whatever else will accomplish this task. 3.Open MozillaFirebird and surf to a site that will use said font. Actual Results: The browser closes without warning or error message. If it was run from the terminal, no error message or information is printed to stderr to allow the user to determine the problem. Naturally, the error does not occur if browser was run as root. Expected Results: If run from the terminal, it might reasonably be expected to have printed a message that suggested something along the lines of a difficulty finding/reading a font. This very well may affect other Mozilla apps.

setting severity: critical adding keyword: crash I don't think this belongs in Firebird, sending to Browser -> General for triage.

boatswain6@yahoo.com: Could you reproduce it with Mozilla TalkBack enabled nightbuild? If Mozilla will crash too, please provide TalkBack incident ID.

This also happens with mozilla/1.4 and 1.5 on fedora core 1. Just found the bugzilla entry after I figured it out myself (testing which html tag would make mozilla crash). Don't know how to activate the talkback.
