I opened the posted file on another PC (w/ Linux, LC2.2.0rc2+) and there was little I can do to stop LC crashing after deleting the 'sideview' layer.  I was successful a couple of times, but generally it crashes when trying to save the file and leaves a file that is much smaller (29.2 kB in my case).  I opened the dxf with a text editor and found the file was truncated in a section related to the layer "Carport2.dimension".  After several attempts I found the file was always truncated at the same place.

Once again, opening the original file and comparing it to the truncated file in a text editor I found the layer label had changed.  From "Carport2.deminsions" in the original to "diminsions" in the truncated file.  Back in LC with the original file, I renamed the layers containing a ".", replacing it with a "-";   "Carport2.deminsions" becomes "Carport2-deminsions", etc.  I was able to delete "sideview', save the file and continue to work with the drawing.

Moral of the story - don't use periods / dots / "." in a layer name (maybe?)

Edit - Never mind.  I tried it again with the same problem...
