Description Dima Ryazanov 2006-05-16 00:45:55 UTC

Version:            (using KDE KDE 3.5.2)
Installed from:    Gentoo Packages
Compiler:          gcc version 4.0.3 (Gentoo 4.0.3, pie-8.7.8) 
OS:                Linux

Finally found a reliable way to reproduce this :)

Open some HTML page. Even this is good enough:
<html>
 <body>
 </body>
</html>

Drag the first node in <body> (even if it's an empty #text node), and try to place it above itself. This should make it the first element again - and therefore shouldn't change anything. Instead, it crashes:

(I hope this isn't a gcc4 bug...)

This often happens when dragging other nodes, too - but not as reliably.


While I'm at it, expect a few more crash reports soon :)

Nah, no gcc bug, just the tree viewer fails to handle DOM exceptions.
