I do not succeed in reproducing it. I saw it just once.

Status changed to 'Confirmed' because the bug affects multiple users.

[Edwin Lee (leeed2001)]

This type of thing happens with me as well. I am using Chrome, not Chromium, but it is the same type of behavior.

My setup:
Ubuntu 12.04 64-bit
google-chrome is default browser
google-chrome is also default program to open html files
google-chrome is locked to launcher

To produce:
I open google-chrome and browse
I then locate an html file on my drive in nautilus and double-click to open it

Expected behavior:
"locked" Google chrome icon shows multiple arrows, indicating that multiple windows are now open

Actual behavior:
A second chrome icon shows up at the bottom of the launcher, which is attached to this html file open instance

Ideal behavior:
The single chrome instance opens a new tab showing the html output. I realize this is likely possible now, and perhaps just related to calling chrome in a special fashion to indicate it should attach it as a new tab instead of a new instance. But let's just get the new instance thing working first!! :)

Additional info:
I don't believe I modified any mime or defaults information manually (in the config files) when setting chrome to the default html opener. Though this definitely looks like confusion between desktop files/bamf and google-chrome reporting itself funny when opened from a file.

Happens to me with Firefox

[Václav Pavlík (pavl-va)]

It happened to me too and I found a solution:

1) Open /usr/share/applications/google-chrome.desktop with sudo privileges in some editor.

2) Open Chromium or Chrome browser. Does not matter, if it shows in a different icon or not.

3) Open a terminal and type:

xprop | grep WM_CLASS

4) Your mouse pointer will change into a cross. With this cross click anywhere inside the Chrome/ium window. Something like this will show up in the terminal:

WM_CLASS(STRING) = "Google-chrome-stable", "Google-chrome-stable"

5) In the editor, in which you opened the *.desktop file, write on the second line (after the [Desktop Entry]):

StartupWMClass=Google-chrome-stable

or StartupWMClass=whatever was in the terminal output (in either of the quotes).

6)Save the file and the result should be seen immediately.

Cheers.

Thank you for taking the time to report this bug. We have tried to recreate this on the latest release of Ubuntu, but cannot reproduce it. This bug is being marked as Invalid. If you believe the problem to still exist in the latest version of Ubuntu, please comment on why that is the case and change the bug status to NEW.

Tested in Chrome, Firefox, Chromium and Opera. It opens in the current tab.
