Kepler

These are Java issues. Both stack traces show the problem being in the
AWT-EventQueue thread.

The one with a useful stack trace has:

Searching google for:
sun.dc.pr.Rasterizer.appendLine dcpr
Comes up with two hits, neither of one is conclusive.

In general, if Kepler or Ptolemy is run and no JNI is used to load
Kepler or Ptolemy .dll and the JVM crashes, then it is a JVM bug.
It is very easy to crash the JVM if Kepler or Ptolemy uses JNI code
that loads a .dll or other shared library.

I'd probably close this one as it is a JVM bug, not a Kepler or Ptolemy bug.

Is there anything I can do to avoid this? I hate saving my work.

The problem is likely specific to the machine, graphics card, OS and JVM.

Try upgrading the JRE that you are using.
The error was from JRE version: 6.0_14-b08, I think Java 1.6.0_15 is out?

Try using a Java 1.5 JRE instead of a 1.6.
Try using different resolutions.
Try using a different graphics card.
Try using a different machine? (drastic, I know).

probably machine specific. not a kepler bug.
