CLI: Assertion failure when starting new download (svn copy)

[nkarthiks]

I identified the bug to begin in the revision r13760 -- r13768 (inclusive) and persists till the latest version r13786. Other than the command below, the environment variable TRANSMISSION_HOME was set to a valid empty directory.

./cli/transmission-cli --download-dir /scratch/knagara/bittorrent --port 8000 --uplimit 250 /homes/knagara/mllogs/file_rand_50MB_2.torrent

If it helps, the gdb backtrace was:
