WFM, (default) current trunk CVS, Linux.

worksforme with linux trunk 20030213 (gtk1) and CVS (gtk2/xft)

Worksforme, too. Do you have a stack trace? Does it cause an X error that's just eated by the mozilla startup script? Assmuming this is real, I'll bet it's Xft-related, not gtk2 related. Text like that also tends to trigger bug 173204.

Can you put the following in your environment and run the test? NSPR_LOG_MODULES=XftFontLoad:5 that will show the fonts that are loaded when rendering that page.

[0x8818678] setting up pattern with the following specification: lang group: x-western adding generic family: monospace point,pixel size: 9,180 slant: roman weight: (orig,calc) 400,100 matched the following (18) fonts: Luxi Mono Nimbus Mono L Nimbus Mono L ZYSong18030 Andale Mono Courier New Courier New Arial Arial Unicode MS Book Antiqua Lucida Sans Unicode Lucida Console Tahoma Courier LucidaTypewriter Gothic AR PL Mingti2L Big5 Standard Symbols L

Hmm, nothing really unusual there.

Start by reducing your font list in /etc/fonts/fonts.conf (or local.conf) to all non-MS fonts till it works. I had a dodgy font that crashed the xft renderer reproduceably. I've noticed that my MS Arial fonts crash the xft renderer. Reporter can you change your Serif/Sans/Monospace to the Bitstream Vera fonts and try again.

The font it was using was Luxi Mono, so I don't think MS fonts are the problem. However, since I upgraded to Red Hat 9 a while ago, I can't reproduce the crash anymore (either with Red Hat's Mozilla or Mozilla 1.4a GTK2). Instead I see a character that has 000C in a box wherever there are form feed characters in a text or HTML file. I find it strange that Mozilla doesn't treat form feed as a whitespace character in HTML documents. I think this is a bug, according to the HTML spec: http://www.w3.org/TR/html4/struct/text.html#whitespace

Kicking over to layout.

*** Bug 223224 has been marked as a duplicate of this bug. ***

does anyone here believe this problem still exists? reporter address is dead.

Oh, sorry. I’m on a totally different system now, but in Firefox 2, I still see a visible boxed “000C” character for form feeds. In Firefox 3, I don’t see anything, so the problem may be fixed.

=> WFM then. Thanks
