Hello everyone. I have a freshly installed Ubuntu 14.04 (only added metacity gnome flashback).

Installation of DraftSight completed successfully, but it crushes on startup.

Here is the  output i get when starting Draftsight from terminal:

 /opt/dassault-systemes/DraftSight/Linux/DraftSight

QGtkStyle was unable to detect the current GTK+ theme.

Crash report is here

Thanks in advance.
