Description Candid Dauth 2006-06-16 15:09:47 UTC

Version:            (using KDE KDE 3.5.3)
Installed from:    Gentoo Packages
Compiler:          GCC 3.4.6 
OS:                Linux

I am using a JavaScript application that works with AJAX and changes a table by adding or removing rows and changing their contents. I noticed that Konqueror crashes after a few changes on the table, which doesn't happen in Firefox or any other browser.

I figured out that the crash was caused by a border-collapse:collapse on the table. When I removed that, Konqueror didn't crash anymore, but it is nevertheless strange that the table width doesn't seem to be rendered correctly. As you can see in the attachment (after clicking on the «Bug!» link at the bottom), tbody (green) has become smaller than table (red). I think the crash has to do with this rendering problem.

I don't have a test case yet that causes the crash, this example only demonstrates the rendering problem. But if someone finds a workaround where the rendering error doesn't occur, I could test if it really causes the crash.

Created attachment 16640 [details]
Test case that demonstrates Konqueror's table rendering problem.

Comment 2 Candid Dauth 2006-06-16 15:46:50 UTC

Okay, I configured an account in the application that causes the crash. Go to http://www.s-u-a.net/login/karte.php?kde-bugs=1 and click in the «System» fieldset on the «Vorige» and «Nächste» links a few times, and Konqueror will crash. I am sorry that I didn't make to reduce that code onto a minimum, but the crash doesn't occur when I remove the setting border-collapse:collapse, which is defined for all tables in http://www.s-u-a.net/login/style/skin.php?skin=default&type=blue_graphics_fixed on line 96.
