Hi Rob,
I have experienced similar problems on a customers repository:
It turns out that another branch had merged the directory before so
subversion thought to replace the files and not to merge.
I try to do some ascii art to visualize the info-flow:
adding dir "test" into branch
|
v
branch 1: ------*--->
/ \
trunk :---------------1-----2->
\ \ /
branch 2: ---------*--
|
adding dir "test to other branch (maybe merged from branch 1?)
1: here test will be added for the first time
2: here test will be replaced
Maybe you can try to set this up as a test to see if this reproduces
your problems..
Also check carefully the creations of a file or directory and look into
the repository in these particular revisions (TSVN repo-browser helps a
lot!).
Best regards,
Peter
