------------------ Additional Follow-up Comments ----------------------------
To investigate further, I replaced the contents of a partially downloaded file
with rubbish. File size and name still the same. Then, after deleting
files.ini* and shared_* again a temp_recovery.
After some time with disk activity but without noticeable download, four chunks
were marked as being finished (light blue in the web GUI). This is clearly
wrong.

Summary: md4's of a file can become inconsistent when recovering temp
Original Submission: Today, a download messed up and a bad file were comitted
for sharing. The file is bad, the md4 sum and the filename differ. To fix the
issue, I deleted all .ini files and recovered temp.
After some minutes, all chunks are marked as good, apparently without any
actual download and the file is marked for commit again.
Trying to debug, I calculated and compared the md4 sums of each chunk by hand
and found the same numbers listed in files.ini. The md4 sum of the whole file
in files.ini fits the file name and the value I get from a seach in the
network, but doesn't fit the actual calculated checksum of the file.
Since it's impossible to mark single files or even single chunks for a
re-comparison with what's on the network, it's hard to find out what's wrong.
"Verify chunks" in the Web GUI doesn't show any sign of activity.
