           Summary: Solid leaks memory in Amarok

           Version: 4.7.0
          Platform: Unlisted Binaries
        OS/Version: MS Windows
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kde-windows at kde.org

Version:           4.7.0 (using KDE 4.7.0) 
OS:                MS Windows

Amarok gains ~4-30KB of RAM usage per second while running in Windows,
irrespective of usage.
Traces point to the wmi backend of Solid:

It appears to be polling devices every second and not removing objects
generated in the process afterwards. Debugger shows:
("/org/kde/solid/wmi/volume/deviceid/a:",
"/org/kde/solid/wmi/volume/deviceid/c:", ...
etc for all devices once per second.

Confirmed by multiple reports in #kde-windows.

Reproducible: Always

Steps to Reproduce:
Open Amarok. Wait.

Actual Results:  
Memory usage grows steadily.

Expected Results:  
Memory usage is approximately constant.
