Description Sten Heinze 2010-05-21 23:00:06 UTC

Version:            (using KDE 4.4.3)
OS:                Linux
Installed from:    Debian testing/unstable Packages

When opening 
 http://forum.o2online.de/forum/posts/list/129001.page
Konqueror hangs with 100% cpu usage for an extended period of time. Only terminating helps. No plugins are installed or loaded.

Reproducable everytime loading the above website. Expected is a normal display of the website, which e.g. works in Firefox 3.6 and Konqueror 3.5.4/CentOS.

Comment 1 Maksim Orlovich 2010-05-22 00:02:08 UTC

Can't confirm.

Comment 2 Sten Heinze 2010-05-22 00:40:56 UTC

Attaching gdb to the Konqueror process results in this bt respectively full bt 
shown below. 
Let me know which other information can be helpful for me to provide.

Comment 8 Sten Heinze 2023-01-05 16:10:34 UTC

I reported this bug over 12 years ago. Since then not only is the website I found the problem with not existing anymore, but also every software version has changed since then and I am not using Konqueror anymore. Please close this bug.
