Application: rekonq (0.4.59)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.10-90.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I use current git of rekonq: 43dc2695d62fd2e4fc01aff608bb2af3e8335040 (Thu Apr 8 02:53:38 2010 +0200)

I tested rekonq by opening a LOT of galleries and images on deviantart.com and one youtube video. The good news: rekonq seems to scale much better than firefox. There is no noticable decrease in performance when opening a lot of tabs.
The bad news: deviantArts JavaScript is very buggy with rekonq (dragging images to your favourites, middle-clicking images in the gallery seems not to raise a mouse-up event). And when I closed the browser window (with all tabs still open) rekonq crashed.

 -- Backtrace:
Application: rekonq (rekonq), signal: Aborted
