Is git-svn using perl?  I have constant problems using perl after a 
rebase.  The problem starts with perl.exe(!) being rebased(!) to
0x50000000(!).  However, when rebasing perl.exe to 0x400000 where it
belongs, it doesn't work either.  Only reinstalling perl helped
afterwards.

Reini, could you please update the perl package so that the executable
is in its default place at 0x400000?
