Comment 1 Tommi Tervo 2011-06-12 21:32:31 UTC 
Seems that you have enabled js-debugger, can you reproduce this bug without it?
Comment 2 Christopher Yeleighton 2011-06-13 11:19:02 UTC 
Konqueror crashes with JavaScript debugger off too.
I am unable to submit the crash report this time because its volume exceeds USHORT_MAX characters.
This probably means that KJS should be stackless (as any script interpreter exposed to scripts from untrusted source, as far as I am concerned).
