Ok, you have found a bug present since 4 Dec 2011

The crash is produced by 2 empty polylines. this "bad feature" permited in old code / dxf lib are not permited in version 2, but bad checked.
Added a patch in master branch solving this issue "commit d21cb572a0"

Solution only for attached dxf:
open the dxf with a text editor and remove lines 56761 to 56800 included.

For all files:
Wait for a new ubuntu daily buid (see http://librecad.org/cms/home/installation/linux.html)
