When visiting the URL http://www.zdnet.com/pcweek/stories/jumps/0,4270,2411217,00.html Mozilla M11 will exit with a segmentation fault. I reached the page by visiting www.linuxworld.com and clicking on "Windows isn't the only game in developer town" under the heading "Net News". I use Debian GNU/Linux 2.2 (kernel 2.2.13) and glibc 2.1.2, window manager is Enlightenment DR0.16. Mozilla was installed using the Debian package for mozilla, version 19991118.M11-2.
Severity: major → critical
changing assignment from nobody@netscape.com to nobody@mozilla.org
[Correcting assignation from "nobody@netscape.com" to "nobody@mozilla.org".]
Using Win95 1999123008, I do not crash, either by going directly to the zdnet URL, or by clicking on this anchor in the Linuxworld page (which opens a new browser window, if that makes a difference): <a href="http://www.zdnet.com/pcweek/stories/jumps/0,4270,2411217,00.html" target=other>Windows isn't the only game in developer town</a> However, the page loads very slowly, completely blanking the canvas four times during loading. [Although I know that there are a number of bugs filed for URLs at zdnet, pcweek, et al].
pontus, 3jrgm or petersen, can you check this with latest build please. Lots of performance work has been done. And this may be better for you now. Go get M13: http://www.mozilla.org/projects/seamonkey/release-notes/

Yes, it flashes while loading for me as well. The page has a linked style sheet and it appears to be the known bug where when the linked style sheet loads we discard the current frames and re-create them

It's not a dup of bug 17309. I saved the page as a local file and removed the linked style sheet: we still have the flicker. Could someone please look into it during the bug contest this week?

Summary: Mozilla M11 segfaults on the given URL → asynchronous stylesheet arrival causes excess repaint
Nope, the summary should not be "asynchronous stylesheet arrival causes excess repaint" otherwise it would be a dup of bug 17309, which is not as I wrote on 2000-02-01 22:23. Changed the summary to "Multiple redraws on ZDNet" and CCd Vidur who has probably seen something like that before.
Summary: asynchronous stylesheet arrival causes excess repaint → Multiple redraws on ZDNet
It could be related to bug 26320 that I reassigned yesterday to Vidur.
I'll take a look at this tomorrow. I did make an attempt at narrowing this down a month ago, and, if memory serves me (heh!), this page was not simply the result of asynch stylesheet loading. However, I never was able to get this down to a simple set of conditions, but maybe another pass at this will produce a better characterization. I'll also look at bug 17309 and bug 26320, and dup if that is the case.
I just tested this site with a 3/1 build and I see no jumping or multiple painting. Like bug 26320 that Pierre suggested might be related, this appears to be fixed now. If anybody else is still seeing this with recent builds please make it known, otherwise marking WORKSFORME. Taking over to help reduce Pierre's bug count.
Assignee: pierre → attinasi
yes. I don't see this anymore either. Marking WORKSFORME. (However, I did notice a small problem with style not being reapplied when the page is reloaded -- opened bug #30308 on that point).
