Unity Dash does not display KDE4 applications in Recently Used

[PJSingh5000]

ISSUE:

Recently used "KDE4" applications do not appear in the Recently Used section of the Unity Dash.

Security & Privacy settings are as follows:
Record file and application usage (ON)
Include: Chat logs (checked); Documents (checked); Music (checked); Pictures (checked); Presentations (checked); Spreadsheets (checked); Videos (checked)

Applications that are impacted include: KolourPaint, KRename, KGoldRunner, Kolf, KSquares, KSudoko, Kalzium, K3b, KDevelop 4, etc.

This issue appears to occur for any application whose *.desktop file is located in:

    /usr/share/applications/kde4

EXPECTED BEHAVIOR:

Recently used KDE4 applications SHOULD appear in the Recently Used section of the Unity Dash.

This is normal behavior for other applications:
- "Regular" (non-KDE4) applications appear in the Recently Used section of the Unity Dash.
- Gnome applications applications appear in the Recently Used section of the Unity Dash.

TEST/RECREATE ISSUE:

1. Install KolourPaint

   $ sudo apt-get install kolourpaint4

2. Install KWordQuiz

   $ sudo apt-get install kwordquiz

3. Log out, and log back in (so newly installed applications appear in Dash)

4. Confirm that Gnome applications appear in the Recently Used section of Dash

   4a. Click the Ubuntu (bfb) button in the Launcher

   4g. On the Home Lens, note that Archive Manager is listed in the Applications section
   4h. Click on the Applications Lens

5. Confirm that "regular" KDE applications appear in the Recently Used section of Dash
   (Normal Behavior)
