Details:
On startup I get a segfault if a file smaller than 1024 bytes is shared.
Here's part of the bt:
#0 0x083241af in tiger_tree_fd (fd=87, len=962, pos=0, block_size=0,
digest=0xb47d10bc "") at src/daemon/common/commonHasher_c.c:89
#1 0x08324204 in tiger_tree_fd (fd=87, len=962, pos=0, block_size=0,
digest=0xb47d113c "") at src/daemon/common/commonHasher_c.c:118
#2 0x08324204 in tiger_tree_fd (fd=87, len=962, pos=0, block_size=0,

#5 0x08324204 in tiger_tree_fd (fd=87, len=962, pos=0, block_size=0,

#6 0x08324204 in tiger_tree_fd (fd=87, len=962, pos=0, block_size=0,

This goes on indefinitely until the segfault. Looking at the code, it appears
that you're not handling the case when 'block_size' < BLOCK_SIZE.
