Erm, actually it showed up in the perl 5.10 -> 5.12 upgrade in Debian,
due to use of -Duse64bitint when compiling the latter and not the
former[1].

To summarize:

 - "$Storable::interwork_56_64bit = 1;" can be used to work around
   that particular brand of breakage;

 - The interwork_* option does not take care of similar cases in which
   a git-svn repository is generated on one machine and read by
   another[2], though.

Hence my happiness at the arrival of Jason's patch.
