The first user-facing symptom: Google Chrome stable is correctly set as the default browser in System Settings / Details / Default Applications as well as in `update-alternatives --display x-www-browser`, yet it keeps complaining about not being a default browser. Clicking "Make Google Chrome the default browser." has no response.
The problem is reported here http://askubuntu.com/questions/688779/google-chrome-stable-keeps-asking-if-it-should-be-set-to-default but the answer is somewhat wrong.
I have successfully reproduced and debugged the problem. I managed to establish that it is connected to xdg-utils, namely to /usr/bin/xdg-settings script.
```

There is a function in /usr/bin/xdg-settings called desktop_file_to_binary() and it has a bug. It is slightly different than the one in the vanilla xdg-utils 1.1.0 rc3. It is implemented in scripts/xdg-utils-common.in.
See line 65 in xdg-utils-1.1.0~rc3+git20150907/scripts/xdg-utils-common.in :
```
command="`grep -E "^Exec(\[[^]=]*])?=" "$file" | cut -d= -f 2- | sed -e 's/ .*$//'`"
```
When executed against google-chrome.desktop or firefox.desktop it results with:
```
google-chrome-stable
google-chrome-stable
google-chrome-stable
```
or
```
firefox
firefox
firefox
```
respectively.
When passed to `which` and then to `readlink -f` it results with no path to the actual binary. In the vanilla xdg-utils package (version 1.1.0 rc3) the `sed` part is replaced with `first_word`. An alternative would be adding `| head -1`.
Then we would have only one `google-chrome-stable` or `firefox` which in turn would result with the actual path to binary resolved correctly and that would make xdg-settings work fine. |

(Existing description has been broken up into sections.)
[Impact]
The first user-facing symptom: Google Chrome stable is correctly set as the default browser in System Settings / Details / Default Applications as well as in
update-alternatives --display x-www-browser
yet it keeps complaining about not being a default browser. Clicking "Make Google Chrome the default browser." on Chrome's settings page has no response.

[Regression Potential]
Limited. The commands after the modified lines assume that there is only one line, so passing the output of the modified lines through `head -n1` should ensure that. In the case of there being 0 or 1 lines before the `head -n1` command, nothing will be changed.
In the worst case, there may exist a .desktop file where the first Exec line isn't the main program (mentioned in comment 2 below). In that case, however, this change will result in the incorrect program being chosen; this may or may not be better than the command not working at all. |
