error when loading dump doesn't display in web interface

trying to load a dump'd svn file into an svn repo which already has data through the admin interface displays
Loading repository from /tmp/dump ..
.. complete.

however, doing it by command line yields the actual result - and the repo is not loaded in:
svnadmin load repo < /tmp/dump
<<< Started new transaction, based on original revision 1
svnadmin: File already exists: filesystem 'repo/db', transaction '1-3', path 'branches'
* adding path : branches ...

Status: 
Closed (fixed)
