I stumbled upon the same problem, using the share in question worked fine until the upgrade to karmic koala. The first meassure i used was to disable locking, which resolved the "file exists" problem, but still created files don't appear after the cache flush, creating folders is working correctly. What type of logfile is needed to diagnose this? Are the secrets in the logfile? I would prefer not to send the secrets with the logfile...
