Reverse merge - Halted due to an unexpected erro

Hi all,

I've just tried to reverse-merge a revision, and I've received the following
message:

svn merge -c -9654 .../tools tools

---- BEGIN CONSOLE OUTPUT -----
This application has halted due to an unexpected error.
A crash report and minidump file were saved to disk, you can find them here:
C:\Users\xxxxx\AppData\Local\Temp\14\svn-crash-log20100831124530.log
C:\Users\xxxxx\AppData\Local\Temp\14\svn-crash-log20100831124530.dmp
Please send the log file to users_at_subversion.apache.org to help us analyse
and solve this problem.

NOTE: The crash report and minidump files can contain some sensitive
information
(filenames, partial file content, usernames and passwords etc.)
----- END CONSOLE OUTPUT -----

I can replicate this very easily with a fresh checkout, and it isn't
revision specific (I've tried another revision and received the same error).

My environment is: Windows Server 2008 R2 (64-bit), svn 1.6.12 (SlikSVN) x64

svn, version 1.6.12 (SlikSvn/1.6.12) X64
