Eclipse was seg faulting on me for the entire day yesterday. The reason was unexpected. I was using java 1.6 instead of 1.5. They recommended 1.5, but I did not expect this would have such a great impact. The problem was caused by either subclipse and subversive, when commiting results. The interesting is that I was using SVNKit, a java implementation of SVN (no JavaHL). Now everything is fixed and stable.
