As far as I can tell, the repository on this machine (which generated the error message copied below) got confused at some point in the past about upper/lowercase on one filename. My SourceForge repository has the filename all in lowercase, whereas this Windows machine had the corresponding file in uppercase. My attempts on this machine to synchronize or update the local repository with the SF repository failed. When I then manually deleted the Window file and attempted to synchronize or update, then SVN asks me to run cleanup first. Clean up attempts (involving the folder which had the offending uppercase file) then fail with this message:
--------------------------- Subversion Exception! --------------------------- Subversion encountered a serious problem. Please take the time to report this on the Subversion mailing list with as much information as possible about what you were trying to do. But please first search the mailing list archives for the error message to avoid reporting the same problem repeatedly. You can find the mailing list archives at http://subversion.apache.org/mailing-lists.html Subversion reported the following (you can copy the content of this dialog to the clipboard using Ctrl-C): In file 'D:\Development\SVN\Releases\TortoiseSVN-1.7.4\ext\subversion\subversion\libsvn_wc\workqueue.c' line 673: assertion failed (checksum != NULL)---------------------------OK---------------------------
