Svn2git core dumps during processing SVN repository

[John Lawlor]

Hi,

As I mentioned in a previous mail I converted a SVN repository back in
March using svn2git, and it ran fine all the way to end. I tried to run the
conversion again using history up to the end of July. svn2git core dumped
with the following:

The crash report shows the following:

END OF CRASH REPORT

Neither the branch it is exporting: 'dan', or the inactive branch 'CDM_3.0'
caused any problems the last time. I am not sure what is happening.
