Comment 8 for bug 764424

I can't figure out if what I see is related to this bug.
I want to open a file in the chromium browser. I drag it from nautilus to the unity launcher, hoping to drop it in one of Chromium's windows, as was in 11.04 (attaching a file to gmail).
What happens is that the Chromium icon gets grayed and I cannot drop the file to it.

If I do it from window to window, without going through the launcher, the file can easily been dropped to Chromium.

What do you think? Does what I describe suited for this bug? Perhaps I should open a different bug (it worked in 11.04)?
