[BUG?] merge with --dry-run fails but without works fine

hi,

i just saw a strange behavior of subversion 0.20.1.
you can reproduce it like this:

svn co https://svn.zebra.datacore.ch/read-only/zebra-ag/trunk zebra-ag
-r 186
cd zebra-ag

if you do:

svn merge https://svn.zebra.datacore.ch/read-only/zebra-pj/trunk . -r
181:182 --dry-run
subversion/libsvn_wc/lock.c:622: (apr_err=155005)
svn: Working copy not locked
svn: no write-lock in: doc <-------------------------- BUG?

if i remove the --dry-run it _works_:

svn merge https://svn.zebra.datacore.ch/read-only/zebra-pj/trunk . -r
181:182
