Description

[Santeri Paavolainen]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12

Trying to print the page http://www.alandsbanken.fi/info/content/fi/service/price-list/ causes firefox to hang indefinitely. Using gdb shows that it is running somewhere in Pango code, and strace shows only that the heap is growing (only system calls are brk() calls).

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.alandsbanken.fi/info/content/fi/service/price-list/
2. Print page

Actual Results:  
Browser hangs up, does not respond and needs to be killed.

Expected Results:  
Page is printed and firefox remains responsive.

Attachment: Hanging web page (saved including images)

Here's the actual page (HTML+images) that caused the hang-up on my browser. I've tested that the bug occurs also on the disk version in addition to the actual web page.

I tested the page on Windows XP with Firefox 2.0.0.11 which hangs too and needs to be killed via taskmgr.

There is something really funny about the page: IE6 will print 17 pages with some parts of it duplicated, layered over each other etc... so the goal probably isn't to get a reasonable printout (which might be impossible if the CSS is completely hosed), but at least FF *should* print the page (however strangely) without hanging completely.

hang confirmed in Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13

works in current trunk. I narrowed the fix on trunk to a one week range:
2007062405 hangs
2007070204 works

bug 285608 was fixed in this range and the main content of the page is contained in a <div> with |float:left|. I believe this was fixed by that bug.

Santeri: this will be fixed in Firefox 3.

Attachment: Somewhat reduced testcase

This is derived from the attachment 310443 [details]. I narrowed the range when this was fixed on trunk to either side of bug 285608 landing:
2007062604 hangs
2007062711 works

The testcase is pretty much the same as some of the duplicates of bug 285608.
