Description Bill Robinson 2005-07-19 10:23:47 UTC 
Version:            (using KDE KDE 3.4.1)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 3.3.5-20050130 (Gentoo Linux 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1) 
OS:                Linux

This simple test page causes Konqueror to hang:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>konqueror - form as table cell causes hang</title>
</head>
<body>
<table><tbody><tr>
<form style='display: table-cell;' >form as table cell causes hang.</form>
</tr></tbody></table>
</body>
</html>

I have tested the form with this style in other places and it seems to consistently cause crashes. This, I believe should be a valid use of style. Even if not supported, this hang should be fixed.

Confirmed on trunk 433373.

This is no crash.

Backtrace from GDB when Konqueror freezes on such a page

The backtrace will keep repeating its last two lines if I press Enter in GDB.
When I kill konqueror with SIGEGV, making the backtrace window appear, it also
never finishes loading, and keeps repeating last two lines.

I can reproduce this bug. I attached a backtrace from GDB.
