Bug Description

[Impact]

The Unity dash can fail to display the icon or title from a .desktop file correctly if it resides under a directory containing a hyphen character.

[Test case]

As an example (on my 16.04 machine):

$ cat << EOF > test.desktop
[Desktop Entry]
Name=Hyphen test
Exec=/bin/true
Type=Application
Icon=/usr/share/icons/suru/apps/256/dash.png
EOF

$ chmod +x test.desktop
$ mkdir ~/.local/share/applications/hyphen-test
$ mv test.desktop ~/.local/share/applications/hyphen-test/

Now, open the dash and search for "hyphen". On my machine, I see the correct icon but no title is displayed underneath.

$ mv ~/.local/share/applications/hyphen-test ~/.local/share/applications/hyphen

Searching for "hyphen" in the dash now shows an entry with the correct icon and title (but also still shows the defunct previous entry without title).

The effect of the hyphenated path seems variable. Some apps show the wrong icon, some have a missing title, some have both errors.

The problem only seems to be with hyphens in the directories. Hyphens in the file itself are fine. See the screenshot - Might and Magic 4&5 has had a desktop file installed under a subdirectory with a hyphen, whereas Heroes of Might and Magic has a desktop file in the root directory but contains a hyphen in the filename. The latter is shown correctly, but the desktop files in the former directory are not shown properly.

[Possible Regressions]
Nothing known.

Thanks for your work on this, but I'm not sure it is fixed 100% yet. For example:

$ cat ~/.local/share/applications/wine/Programs/GOG.com/Might\ and\ Magic\ 4-5/Might\ and\ Magic\ 4-5\ -\ World\ of\ Xeen\ \(Full\ Speech\).desktop
[Desktop Entry]
Name=Might and Magic 4-5 - World of Xeen (Full Speech)
Exec=env WINEPREFIX="/home/neil/games/mm45/wine" wine C:\\\\windows\\\\command\\\\start.exe /Unix /home/neil/games/mm45/wine/dosdevices/c:/users/Public/Start\\ Menu/Programs/GOG.com/Might\\ and\\ Magic\\ 4-5/Might\\ and\\ Magic\\ 4-5\\ -\\ World\\ of\\ Xeen\\ \\(Full\\ Speech\\).lnk
Type=Application
StartupNotify=true
Path=/home/neil/games/mm45/wine/dosdevices/c:/GOG Games/Might and Magic 4-5/DOSBOX
Icon=C399_goggame-1207661233.0

$ ag -g C399_goggame-1207 ~/.local/share/
/home/neil/.local/share/icons/hicolor/48x48/apps/C399_goggame-1207661233.0.png
/home/neil/.local/share/icons/hicolor/256x256/apps/C399_goggame-1207661233.0.png
/home/neil/.local/share/icons/hicolor/16x16/apps/C399_goggame-1207661233.0.png
/home/neil/.local/share/icons/hicolor/32x32/apps/C399_goggame-1207661233.0.png

But the correct icon does not show. Instead, I get the generic "toolbox" icon as per screenshot attached. Oddly enough, my testcase in the original posting does display the correct icon. Perhaps this is because I specify the full path?
