The dialog box says:
Location information has been specified incorrectly.
svn: E210004: Number is larger than maximum
Keep location anyway?
This just started to occur. I updated the SVN server to 1.8. It was working fine with 1.7.9. I'm using svn+ssh. I have the latest updates (todate) of SVN Subversive and connector SVNKit 1.7.9.
BTW, this still works from the command line just fine.
