Bug: git-svn clone --preserve-empty-dirs fail - couldn't truncate file at /usr/share/perl5/Git.pm line 1337.

Hi, i am in the middle of a migration project. Almost over 60 projects (aprox 1/3) suffer from this behaviour. I was able to create a svn repository dump (8MB) of a small project thats provoke that failure. The failure do not occur if the option "--preserve-empty-dirs" is omitted. Also no problem if the svn dump is filtered with "svndumpfilter --drop-empty-revs" before load into a fresh repo.

I'll be able to provide the dump for further investigations. I would send it on demand. I'm able to reproduce the failure with the dump. It seemed many others had suffered from this bug.
