This bug just happened to me too in a fresh installment of kde 4.1 final but is not only with video-files but with any large file too (it happens with .iso image too and other large files) and it not crash immediately but it hangs for 1 minute or so but if i do the same thing some more times it will eventually crash.
I agree with kmartinsson, the problem is the Information panel, when i'd close this panel Dolphin works well.
Too bad they didn't fix this in the RC1.
PD: sorry for any misspelling, the English is not my native language.
