Subject: Fix rename detection.
X-Git-Tag: v0.3.0~101
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=c195a65dc54ef2ad7f0e96fa63d45a580a3dac37;p=paraslash.git

Fix rename detection.

If a file is renamed and re-added the old code would segfault because of
a NULL pointer dereference in save_chunk_table(). Fix is trivial.
