** Description changed:

When gnome-system-monitor started it uses about 52-53Mb of memory. While
it is running for a long period of time the amount of memory used by
gnome-system-monitor is continuously growing. In ten days gnome-system-
monitor uses already 7Gb. It makes the system start to use swap and it
makes a negative impact on the whole system performance. After closing
gnome-system-monitor and starting again it uses about the same 52-53Mb
of RAM.

It is noted that the memory consumption is growing significantly if the
Resources tab with charts is opened for a long period of time. If the
Processes tab is opened then there is a very small growth of memory
consumption, probably even within the margin of error.
+
+ Steps to reproduce:
+ 1. start gnome-system-monitor application
+ 2. open Processes tab
+ 3. find gnome-system-monitor process and remember how much memory it consumes
+ 4. open Resources tab and let it opened for a period of time. (1 hour, 4 hours, night, 1 day or more) Keep the application window opened somewhere on the screen as if you are monitoring charts.
+ 5. when a period of time is passed open Processes tab
+ 6. sort processes by Memory column
+ 7. find gnome-system-monitor process and check how much memory it consumes and compare with the number from step 3
+ 8. go to step 4 to continue test for a longer period of time or stop the test with current results

Expected Result:
gnome-system-monitor uses about the same RAM regardless of how much time it is working
Actual Result:
gnome-system-monitor uses 7Gb of RAM after 10 days of working while right after start it normally uses about 52-53Mb of memory
