LibreCAD crashes: Segmentation fault (core dumped)

[Pál Csányi]

Hi,

on Ubuntu 12.10:
Description: Ubuntu 12.10
Release: 12.10

when I use LibreCAD version:
apt-cache policy librecad
librecad:
  Installed: 2.0.0~alpha4+yeslib20121014+39cad0f-0ubuntu0~daily7~precise1
  Candidate: 2.0.0~alpha4+yeslib20121014+39cad0f-0ubuntu0~daily7~precise1
  Version table:
 *** 2.0.0~alpha4+yeslib20121014+39cad0f-0ubuntu0~daily7~precise1 0
        100 /var/lib/dpkg/status
     1.0.2+nolibs-1build1 0
        500 http://archive.ubuntu.com/ubuntu/ quantal/universe amd64 Packages

 it crashes frequently with message on xterm from where I start it:
Segmentation fault (core dumped)

I expect to work further in it, but it crashes suddenly.
After crash happen when I start again LibreCAD I can open the previous file but I get not the previous state: I loose the drawings that I made before the crash.

I don't know how to get any further information to help debug this behavior?

Crashes seem to happen when selecting and modifying various entities: moving corners of a rectangle or ellipse, moving entities around, copying and pasting, etc. Crashes do not seem to occur while drawing new entities.

It is necessary to save frequently to avoid loss of work.
