The general rule is that if a crash like that occurs in both the release 
version (which is 3.0.1, not 3.0.0) and R-patched, you should file a bug 
report.

If it only occurs in R-patched or in R-devel, then a message to this 
list is probably better.

If it only occurs in the release but not R-patched, then no report is 
necessary:  it has been fixed.
