I've tested the Opera-Browser the last days and had the same error, too.
There was no "fscommand" or something shown, but the Opera-PopUp-Blocker was activated and activated in a endless loop. I had to kill the Opera here, too.
So the problem seems to be a Flash-Problem with KDE 3.4 / Suse 9.3.
By the way,
www.n-tv.de isn't an unimportant site. N-tv is the German doughter of CNN.
I have to congratulate Konqueror to it's speed. It is not really slower than Opera. But there are three features that could be improved:
1.) An in-page-search is strongly needed within the menubar or an extra toolbar.
I believe there isn't even a short-command for the address-line to search within a page?
2.) The back-button could work immediately withour re-loading the old website, which is already in the cache.
3.) Downloading during the save-as-dialoge is shown.

Flash-Ads are not very convenient, too :-)
