Eclipse continue crashing
Check bug report https://bugs.eclipse.org/bugs/show_bug.cgi?id=404776 . I suggest you to upgrade to the newest Eclipse 4.3 (Kepler).
Alternativelly you can try workaround suggested in comment #6:
For a workaround add the following to the end of your eclipse.ini
-Dorg.eclipse.swt.browser.DefaultType=mozilla
Upgrade to 4.3 or 4.4 works better, since for some Eclipse projects it continues to crash (egit, ADT...). If you are running old version of Eclipse I suggest you to delete the old installation and reinstall new version of Eclipse.
Install latest Eclipse in Ubuntu 14.04
