bzr fast-import crash

ls -l ~/cvs2svn-2.1.1/cvs2svn-tmp/

These files were generated using the cvs2svn tool with a slightly modified options file. It took several hours to run, which did not seem unreasonable bearing in mind the size of the repository.

Then:

mkdir bzr4
cd bzr4
bzr init
bzr fast-import ~/cvs2svn-2.1.1/cvs2svn-tmp/bzr-blob.dat
 bzr fast-import ~/cvs2svn-2.1.1/cvs2svn-tmp/bzr-blob.dat
