[svn] Subversion stuck due to "previous operation has not finished"?

I had the same issue, what worked for me:

  1. Copy your folders and files to another place, say to a folder (I changed my files recently and the commitment failed and led to the addressed problem)
  2. check out a new working copy
  3. copy your changed files from folder to your working copy and override existing files. Commiting / Updating should work now
