[libredwg] Getting empty output

[Davinder Kumar]

@All i am struggling with a problem from many days that whenever i
used testSVG for converting dwg to svg
A file is created in example folder with name ouput.svg(in my case) i
got the following error
1.It shows empty file in browser means empty browser(i am using
Mozilla Firefox for opening of svg)
2.XML Parsing Error: no element found
Location: file:///home/hanuman/Desktop/libredwg/examples/sample1.svg
Line Number 1, Column 1:
^
3.Segmentation error
That is all in the case of that dwg file that is supported by my
running libredwg.
4.<error-code>
