What can I do about the "Working copy not locked; this is probably a bug, please report" SVN error?

I am trying to commit my entire project to Subversion, and I get the following error message after clicking SCM > Commit Entire Project:

Error: 155005 (Working copy not locked; this is probably a bug, please report) Description: Commit failed (details follow):

Error: 155005 (Working copy not locked; this is probably a bug, please report) Description: Directory '/Su开发者_JAVA百科bVersion/SplitView/trunk/SplitView/build/SplitView.build/SplitView.pbxindex/.svn' containing working copy admin area is missing

Does anyone know how to fix this bug?

See this article. You've deleted your .svn directory.
