Cairo: clicking the Chromium launcher opens an application icon instead of just marking the launcher with arrow

Hello,
Thank you for having reported this bug!
Can you edit Chromium launcher (right click on it) and have a look at the application class (Extras Parameters). You can click on 'Grab' and select Chromium window.
BTW I think that Chromium doesn't use a strange class and it should be "Chromium-browser" (the same name as the launcher and its command). If it's not the case, which version of Chromium do you have and what's its class?

Thanks, it was so easy! I grabbed the window and the Application launcher immediately disappeared. It looks like the problem was that the Program class was set to "Chromium" insted of "Chromium-browser", because grabbing the window has changed it to "Chromium-browser".

@Chromium team: Hello,
It seems that StartupWMClass value in chromium-browser.desktop file is not correct because the right class is "Chromium-browser".
You can verify it with this command:
  $ xprop |grep CLASS
(the class is the second value or directly with this one: $ xprop |grep CLASS |cut -d, -f2).
BTW, StartupWMClass parameter is optional because the class is the same as the binary (and the icon) with the first character capitalized.

It affects the trunk branch lp:chromium-browser (http://bazaar.launchpad.net/~chromium-team/chromium-browser/chromium-browser.head/annotate/head:/debian/chromium-browser.desktop) but also all other branches linked to the Chromium-Browser project on launchpad (https://code.launchpad.net/chromium-browser) and maybe also some other distributions which use this file!

Fixed in the .head branch. It will 1st appear in the next valid daily build (tomorrow).
Please test then and report here so i can merge the fix in the other branches.

Thank you Fabien for this quick fix. It's now correct!

chromium-broswer has been accepted into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I performed the following with 5.0.375.70~r48679-0ubuntu0.10.04.1 from -proposed:
$ xprop | grep CLASS
WM_CLASS(STRING) = "chromium-browser", "Chromium-browser"

so this passes the test case. Marking "verification-done".

This bug was fixed in the package chromium-browser - 5.0.375.70~r48679-0ubuntu0.10.04.1
