I find that I have to start Maestro with -SGL option, otherwise Maestro terminates with segmentation fault errors. I am also having some graphics problems.

Segmentation fault
Maestro: Error while running Maestro
Maestro: ** abnormal termination **

What might be the problem?

You might experience these problems with unsupported Linux platforms. See the Installation Guide for the list of supported platforms, or the Download page of our web site.

Sometimes a segmentation fault is seen when certain 32-bit libraries are missing from a 64-bit Linux installation. If you install the 32-bit version of Maestro (the only version available in Suite 2009 and earlier) it requires some 32-bit compatibility libraries. The following 32-bit packages had to be installed on a RHEL 5.3 system to make it work with Maestro:

libXmu-1.0.2-5.i386
libXpm-3.5.5-3.i386
libXaw-1.0.2-8.1.i386
mesa-libGLU-6.5.1-7.7.el5.i386 -or- xorg-x11-drv-nvidia-libs.i586

Please check your OS installation media for similar packages.

Note the ".i386" part which indicates that these are 32-bit libraries and are different from ".x86_64" 64-bit packages that most likely are already installed on your machine.

The 2010, 2011 and 2012 releases of Maestro have both a 32-bit and a 64-bit version for Linux; the correct version is automatically selected when you run Maestro. From 2013-1, only a 64-bit version is distributed for Linux.

The fact that Maestro opens with -SGL and that you are getting graphics-related errors suggests that you don't have graphics drivers with hardware-accelerated OpenGL installed properly. You can keep using Maestro with -SGL for the most part. However, if you would like to enable hardware acceleration, you need to download the latest driver for your card appropriate for your Linux system.
