Here's some more detail.

I removed /var/lib/backuppc/pc/ralph2/38/f%2fdata/attrib to see what 
would happen.  Things progressed farther but still hung at the end of 
the run for this filesystem:

Skipping legal/incidents/Yelverton 927285 SZ24HON52  04031288---Stiles 
Outdoor  4-25-11/photos rec'd 4-26-11/hustler fire stiles 9.jpg (same attr)
Sending csums, cnt = 0, phase = 1
Child is sending done
Got done from child
Got stats: 3513074128 269879412 669155153 0 ('errorCnt' => 
0,'ExistFileSize' => 0,'ExistFileCnt' => 0,'TotalFileCnt' => 
0,'ExistFileCompSize' => 0,'TotalFileSize' => 0)
finish: removing in-process file .
Child is aborting
Got exit from child
Done: 0 files, 0 bytes
Got fatal error during xfer (aborted by user (signal=INT))
Backup aborted by user signal

Any ideas?
