On a black background, a white (#ffffff) rectangle with 50% transparency (Mix) is darker than a 50% white (#808080) rectangle. Shouldn't it look exactly the same?

Oh probably. But it is more of an eyeball thing where you know it's the right amount when you see it.

Anyway that is very good question like that precisely :-) Finally the vector graphics based on math so really why it does not exactly the same?
To me the one on the right looks darker, Mike. But I sampled both and I was wrong.
I can confirm Mike's results in DPX9.

This is using version 6. I don't have a version before 6 to try.
I didn't save my original test case, and lost it (computer crashed). Now I cannot reproduce the issue anymore. It could be that I did something wrong or that there is a strange bug in 5.1 which only manifests itself under certain circumstances.
Time to Upgrade.
I did a test of various options and did find a 1 point difference in a few of the resultant colors but these may have been rounding off issues.

maybe depends how you do it
for example, if I type in 808080 in the colour editor to set the second square, I can see a very slight variation, and this may be because when I look at the HSV value it is H-0 S-0% V-50.29%
if I then reset the HSV to H-0 S-0% V-50% exactly the slight difference disappears [the hex value displayed remains at 808080]
-------------------------------
Nothing lasts forever...
I set gray scale intensity to 50%, and the result was #808080 for RGB. But the difference to the 100% white 50% transparent object was big, i.e. not just a rounding error.
