Further testing reveals this to be a TortoiseSVN issue. When the scenario is recreated
using a script and the SVN command line client, we see :

svn: No such revision 3
Sending testwcs/mytest/file1
Transmitting file data .svn: Commit failed (details follow):
svn: Base checksum mismatch on 'file1':
   expected: c2ff4b361ea9984f93b6a1e2a5c77a92
     actual: f14c077f10dcaad0ce42856b52cb50f4

Tested at 0.31, 1.1.3, 1.1.4.
