CIRCLE TAG

good night ..

It was there that when using the program Inkscape to the format of a circle not he labels as the tag circle .... then the time to draw an image that will be used in a device with the Symbian operating system, such as the smartphone the nokia n95, using the format of a circle he does not recognize this device ...
I understand that the code to generate the labels do tag it to circle ....
Well do not know if I am sure .. but already tried all the ways to make a single circle as icon to put in my project, which would be for an application for the operating system symbian and even then it does not recognize the circle and ... to make use of this code below to create the design in svg, or a circle, and works is recognized by operating system the device.

<svg xmlns="http://www.w3.org/2000/svg" width="100" height="100">

  <circle cx="50" cy="50" r="45" stroke="#000" stroke-width="3" fill="#FD0" />

</svg>

thanks
