I'm using Intellij IDE 12.01 and I'm not able to check out my project from subversion server.
I don't know if it's because I'm behind a proxy but some statements found about SVNKit made me think so.
I set up global proxy settings and told version control / subversion to use these settings.
Updating of IDEA worked, so internte connection works through proxy.
But checking out with subversion doesn't.
I have it so far to ask me for username and password but I got stuck at:
'Cannont check out from svn:svn: E175002: REPORT of '/svn/xxxx/!svn/vcc/default': 400 Bad Request (http://xxx.de)
Checking out with Eclipse and Subversive works :-(
