Strange log "path not found" behaviour

I'm getting a strange log path not found behaviour if I query for
multiple revisions:

i:\>svn log https://server/svn/core/base/trunk -r7114
------------------------------------------------------------------------

i:\>svn log https://server/svn/core/base/trunk -r6818
------------------------------------------------------------------------
r6818 | chris | 2012-05-31 15:27:16 +0200 (Thu, 31 May 2012) | 1 line

svn: E160013: '/svn/core/!svn/rvr/7114/trunk' path not found

i:\>svn log https://server/svn/core/base/trunk -r7114 -r6818
svn: E160013: '/svn/core/!svn/rvr/6818/base/trunk' path not found

(I've replaced the actual message with #)

The path changed between the two revisions (trunk was moved to base/trunk).

Running the log separately is OK but I get an error when combining them
- shouldn't they both behave the same way?
