Version 2.1.0 seems to cause segmentation faults with unknown reason, log[1].
According to the github issue[2], a workaround is to stop logging qt message by commenting out /usr/lib/python3.6/site-packages/gns3/qt/__init__.py line 298 which is log.info(msg_string). The filename and line number are inferred from the log[1].

Upstream has split development of the major versions 2 and 3. This package will keep tracking the latest version. If you prefer version 2, there is now a separate package gns3-gui-2.
