Hello guys,

we have to turn some projects managed by Subversion into a GIT-based solution. However the conversion unfortunately fails with an error:

============== %< ==============
[...]
Found branch parent: (refs/remotes/origin/tags/v_2.1.1) 
450fa2c84a8fc087a2a66e5fb3d6d22096671f81
Following parent with do_switch
        M       changes.xml
        M       pom.xml
couldn't truncate file at /usr/lib64/perl5/vendor_perl/5.20.2/Git.pm line 
1325.
$ git --version
git version 2.5.0
============== %< ==============

Apart from the line number, the same error occurs also with GIT version 2.4.6 and 2.3.6 (latest stable version in Gentoo).

The command to create the GIT repository was: ============== %< ============== $ git svn clone http://websvn/svn/essvn/standard/java-commons/lang -s --no- metadata --preserve-empty-dirs -A ~/tmp/authors.txt commons-lang ============== %< ==============

Note, that the command succeeds even for 2.4.6 if we drop the --preserve- empty-dirs option - at the cost of some empty directories which are used to trigger profiles for Maven; i.e. without those we cannot reproduce released versions.

Cheers, Jörg
