Already fixed in TRUNK
I'm also having this problem and I really can't get any further before CR2 is released or I can download from trunk.
Currently I'm not able to download from the svn repository:
C:\dev\tmp>svn export http://anonsvn.jboss.org/repos/messaging/trunk
svn: REPORT request failed on '/repos/messaging/!svn/vcc/default'
svn: REPORT of '/repos/messaging/!svn/vcc/default': Chunk delimiter was invalid (http://anonsvn.jboss.org)
This seems to be related to http://subversion.tigris.org/faq.html#tiger-apr-0.9.6
Is the fix (patch) attached to any jira issue?
CR2 has been released
