while testing a java applet using live connect, I got a konqueror crash in the
javascript interpreter.
See http://www.n-tv.de
At the right side of the page, if you scroll down, you will find an image link
labeled "Teletext". If you click on this link, a new window opens and
should display a set of java applets. Due to another problem since some days,
not all components of the page are loaded the first time. You may have to
reload the page or to click the link 'teletext' in the upper left of the
window. If you close this window, the crash occurs.
It seems that elements of the window are referenced which are already deleted
or the timer event should not be executed anymore.
Stack trace follows. Look at Frame #27.
regards, till
