Alarm or Timer doesn't stop when "Stop All Alarms" is used and "Repeat Sound" is unchecked.

When I use "Stop all alarms" from the notification area icon's menu, the main interface of the application doesn't show that the alarm has actually stopped. Then, when selecting an alarm and clicking "Stop" in the main UI, the tray icon begins to blink. Using "Stop all alarms" again finally causes the tray icon to cease blinking. Interestingly, this only occurs when "Repeat Sound" is unchecked in the alarm- or timer-specific options.

Steps to reproduce:

1) Kill and restart applet.
2) Create a timer named "test2", with a delay of 5 seconds, playing the sound sonar.ogg, and uncheck "repeat sound".
3) Start the timer from the main UI.
4) Wait 5 seconds.
5) Right-click the notification icon, and select "Stop all alarms".
6) Observe that while the icon stops blinking, the alarm "test2" is still enabled and blinking in the main UI.
7) Disable "test2" by selecting it and using the Stop button.
8) Observe that the notification icon begins blinking again.
9) Finally, access the "Stop all alarms" notification icon menu function again to stop the tray icon blinking.

10) Repeat the process with "Repeat Sound" enabled in the timer or alarm's options dialog, and observe the bug does not occur.

Debug output from the applet is attached.
