Most likely, it had nothing to do with another teammate who put something in the SVN repository in order to affect your working copy.
Working copies are a great Subversion innovation, but sometimes they just break down from usage and abuse, and a new check is required. This can be exacerbated if you have local changes.
Now obstacles can be caused by several things. Firstly, the working copy is simply won. He broke it, cleaning will not fix it. Secondly, it can become an obstacle because you have another window, application, or process that holds the file or directory that you are trying to commit. This is especially true for Windows and TortoiseSVN.
Are you sure that you did not have command line windows, other applications, or even Windows window files listed in these directories?
