"Could not read status line" error when trying to commit locked file

I'm using svn locking for the first time. I can lock and unlock files, but I get an error if I try to commit a file that's locked:

$ svn lock report.docx 
'report.docx' locked by user 'lorin'.

Ed开发者_StackOverflowit, edit, edit...

$ svn st
M    K  report.docx
$ svn commit -m "Edited the introduction"
Sending        myproject/report.docx
svn: Commit failed (details follow):
svn: CHECKOUT of '/reports/!svn/ver/6049/myproject/report.docx': Could not read status line: Secure connection truncated (https://www.example.com)

If I unlock the file, then I can commit.

It looks like you are using Locking correctly (at least according to the docs). I would question why you are doing that with SVN, but that's not your question. ;)

Have you checked out this SO thread that had a similar error?

Please be informed that the Subversion lock and unlock commands do not work properly in an environment where replication is being used. Subversion does not currently provide a means for replicating locks between repositories, or even via repository dump files. Consequently, locks are all stored in the master repository and they do not exist on the replicated repositories.
