UPDATE:

After clicking the "Load Plugin" button in the first movie, you have to use a mouse wheel (or keyboard) to scroll the page and then rekonq crash.

Not crashing for me. 
Archlinux current. KDE 4.6.2, 32bit flash 10.2.159.1. Qt 4.7.2, zen-kernel 2.6.38.4-zen+.
Comment 4 Unknown 2011-05-02 19:18:01 UTC 
To clarify: rekonq doesn't crash at this site with "auto load plugins" option enabled, only when "manually load plugins" is enabled.

Comment 6 gleirsch 2011-06-04 19:35:35 UTC 
My rekonq (0.7, KDE 4.6.3, 64bit, kubuntu 11.04) also crashes frequently on pages with flash objects in it. As I could not find debug symbols for rekonq and libflashplayer, I was not able to submit a DrKonqi defect report. Maybe the trace below (in particular Thread 1) shows a tight relationship to the above issue:

New crash information added by DrKonqi

rekonq (0.9.1) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:
There were two youtube videos on page. I have loaded flash plugin for first video (it was successfully played) and then clicked button to load second video and rekonq crashed.
- Unusual behavior I noticed:
When I clicked second load plugin button, first video was played for a second before application crashed.
- Custom settings of the application:
Manual loading of plugins is used instead of automatic.
