Eclipse & SVN

What a bear Eclipse/Subversive/SVN is.  When using svn+ssh with Eclipse, there is a file which must have group-writable permissions:

/path/to/svn/db/rep-cache.db

This took a long time to debug.  I hope that none of you have this insane problem, but if you do, the symptom of this problem is that Eclipse will not allow you, using Subversive, to commit files.  Something about writing to a readonly database.
