I am getting a strange error while uploading files to Tahoe today.  The error is:

"UploadUnhappinessError('shares could be placed on only 9 server(s) such that any 7 of them have enough shares to recover the file, but we were asked to place shares on at least 10 such servers. (placed all 12 shares, want to place shares on at least 10 servers such that any 7 of them have enough shares to recover the file, sent 10 queries to 10 servers, 10 queries placed some shares, 0 placed none (of which 0 placed none due to the server being full and 0 placed none due to an error))',) (profiles_activity.frm)"

My client settings are:

shares.needed = 7
shares.happy = 10
shares.total = 12

Actual available storage servers: 16

What is strange about the error is that it shows that 10 shares were placed and that there were 0 errors.  However, I get an unhappiness error.

The part of the error message that has me confused is:

"sent 10 queries to 10 servers, 10 queries placed some shares, 0 placed none (of which 0 placed none due to the server being full and 0 placed none due to an error)"

It can happen that the happiness achieved is less than the number of shares placed, but in that case the error message should be showing that some servers didn't accept shares in the first-choice placement.
