Comment 3 for bug 203967

Ok, so it turns out that kdelibs has a built-in detection feature for flash that we would be extending with our patch to prompt for flash installation with our tools. This detection, however, tends to be broken unless a website explicitly tries to embed a Shockwave Flash object. Some sites like Youtube, however, check to see if flash installed first via javascript before deciding to embed the flash object. Since Youtube chooses not to try to embed the flash object KHTML never detects it, which is the bug.

This probably should get an upstream bug report.
