It happends when the general settings for Rectangle object: "Style of new objects"=="Last used style" and when last used style actually was a path where start marker or end marker was other that "None".
I upload a sample document. Over the years I've being used Inkscape I got used to the XML editor, so I know that a workaround for this specific file is:
* Open XML editor when rectangle object is active.
* Find the "Style" atribute and open it for editing.
* Delete the excact string: "marker-start:url(#DotM-3)" (make sure there is not a double sami-colon, so delete either one before or after.
The contents of the Style attribute should then be excactly:
"color:#000000;color-interpolation:sRGB;color-interpolation-filters:linearRGB;fill:#e6e6e6;fill-opacity:0.72131144;fill-rule:nonzero;stroke:#0000ff;stroke-width:1;stroke-linecap:butt;stroke-linejoin:miter;stroke-miterlimit:4;stroke-opacity:0.23497267;stroke-dasharray:none;stroke-dashoffset:0;marker:none;visibility:visible;display:inline;overflow:visible;enable-background:accumulate;clip-rule:nonzero"
