When I visit the page from the url in many cases Mozilla freezes. CPU usage is at about 100%. When it doesn't freeze, it crashes in the IL_GetNaturalDimensions function. Sometimes it loads correctly without a freeze or crash. Here is a log with stack trace report from Dr. Watson for Windows 2000: Application exception occurred: App: mozilla.exe (pid=1564) When: 29.1.2001 @ 11:21:16.779 Exception number: c0000005 (access

I'm using Mozilla 2001012820 on Windows 2000 SP1 on PC.

CCing pavlov@netscape.com. I was told that he is working on a new imagelib and should know more about this.

I can confirm this bug on Linux, using build 2001012906. Does not crash always as described...

I also can confirm this on linux but at a different site (http://www.openuniverse.org/) This crashes everytime for me.

I tried with the site that Gregory mentioned and Mozilla behaves the same. I was also expiriencing this on http://www.amdzone.com/ yesterday (or two days ago) but can't see the problem today. Gregory also thinks it's a regression so I am adding the keyword and setting Severity to major. I'm also thinkking about adding keyward crash. Any comments about it?

Is this the same problem as bug 66792?

*** Bug 67011 has been marked as a duplicate of this bug. ***

All pnunn bugs reassigned to Pav, who is taking over the imglib.
