This is not an Unity/BAMF bug.
New chromium doesn't seem to support anymore the --class parameter, as
you can see checking the windows with "xprop WM_CLASS".
Please fill a bug upstream, since we can't do anything at Ubuntu level
to recognize these instances as different.

Chromium aura doesn't honor the --class parameter anymore

Bug description:
At Ubuntu 13.10, I could have different instances of chromium (with
different profiles) have separate icons in unity. All I had to do was
change the StartupWMClass= and the --class= in the exec= line in the
desktop launcher. Starting with 14.04, Unity ignores these values and
groups the chromium windows together. Similarly, webapp instances
(created using file-> create application shortcuts) are also grouped
under the one chromium icon. This beats the purpose of webapps, as it
makes it much more difficult to regard a webpage as an application.
To replicate:
1. copy the chromium-browser.desktop to two different locations: 1.desktop
and 2.desktop.
2. Edit 1.desktop to the following values:
Exec=chromium-browser --temp-profile --class=Other %U
StartupWMClass=Other
3. Edit 2.desktop to the following values:
Exec=chromium-browser --temp-profile --class=Other2 %U
StartupWMClass=Other2
4. Start both from nautilus or from the desktop.
In 13.10, this results in separate icons on the launcher, in 14.04,
only one.
It seems that I'm not the only one to encounter this problem:

launcher-of-14-04-lts
And this is further evidence that the icons were separable in previous
versions: http://ricardofeliciano.me/how-to-create-a-unity-launcher-
icon-for-each-chromechromium-profile-in-ubuntu/
