Comment 5 for bug 930491

I have the same problem. The top command shows nm-applet starting below 2% memory usage of 1GB memory and slowly rising over time. I have recorded nm-applet memory usage at plus 26% of 1GB of RAM.

At plus 9% memory usage the network app indicator menu becomes unresponsive. It is not possible to disconnect either the wired or wireless connection, or disable networking or wireless. Clicking on these lines in the menu has no effect. It is still possible to disconnect using the slider options in the System Settings Network utility but once switched off by using that utility wired or wireless connections cannot be switched back on using the network app-indicator menu but only by the System Settings Netwrok utility.

Furthermore, if the menu is left open it blinks out of existence and then re-appears and does this frequently but not rapidly.
