Here is a testcase demonstrating crash (100% CPU usage, Konq hanged) for 
KHTML/Konqueror.
Save all attached files to disk, and run table-xml-demo-bad.xml in Konq.
As it's size just 252 bytes, I believe it's very close to minimal testcase 
(while still shows something on screen when slightly modified :-)

at the same time, table-xml-demo.xml and table-xml-demo-2.xml are rendered by 
Konq without any heavy CPU usage, and display one paragraph and 
CSS2-formatted table.
There is a rendering bug, though, with table-xml-demo.xml.
Paragraph with Navy-colored text should go first, but it displayed second, 
after table (there is no display: table element in that example, it's 
anonimous)
You can compare these examples in Mozilla - it renders them in similar way.
