This is very likely a dup of issue #1421. In this mail http://www.contactor.se/~dast/svnusers/archive-2003-07/0142.shtml ...Joey Hess describes how cvs2svn.py errored trying to convert his repository. The error looked like this: svn: file not found: transaction `8c', path `branches/potato/Client/dpkg-reconfigure.8' We've seen errors like this before; it means cvs2svn is constructing a dumpfile that tries to change a path it has already deleted (or never created). See issue #1421. Joe's repository is only 1.8 MB, and he's put it here: http://kitenet.net/~joey/tmp/debconf-cvs.tgz Yay! That's small enough to make reproducing the bug not burdensome.
