small memory leak in unity-panel-service per use of global menu

[Doug McMahon]

Binary package hint: unity

Every use of the global menu increases memory used by unity-panel-service by about 1MB per use
If desired can provide log

It's also been reported and seen here that in the Classic login each use of the global menu does about the same for indicator-applet-appmenu

Confirming on classic desktop.

indicator-applet-appmenu had grown to use 786MB of RAM over the course of 3 days.

[Chris Coulson (chrisccoulson)]

Some of these leaks are in dbusmenu (branch pushed for those), although I think some of the remaining leaks are in unity + various indicators too

[Chris Coulson (chrisccoulson)]

Closing the unity task and reopening the libdbusmenu one. The other bug leaks are also there too.

[Eric Appleman (erappleman)]

Yup. Still getting 100+ MB memory leaks with the appmenu.

[Sebastien Bacher (seb128)]

is that still an issue?

[pablomme (pablomme)]

unity-panel-service consistently uses 31 MiB of memory on my system, so I would say the issue is gone.

[pablomme (pablomme)]

...hence all tasks should be closed.

[Regular User (dot.ru)]

unity-panel-service is taking ~120mb of ram right now. This wasn't happening before (I do monitor my system resources regularly). I'm on a laptop and it's been up for 15hrs. For the record, I enabled the old system tray functionality right after installing the system a couple of weeks ago, don't know if this has anything to do with this issue.
