Bug and question about branching an SVN repository

I am trying to work on the source code of PrestaShop:
http://www.prestashop.com/en/
I used a command line client for SVN (SilkSVN, was 1.5.4, just upgraded 
to 1.6.16) to get the branch:
http://www.prestashop.com/en/downloads/#svn

Then, I issued this command:
 > bzr branch official Philho

to get a work branch. I first tried in a shared repository, then I just 
deleted the .bzr above to see if it is better without that, no luck.

It starts to import revisions from SVN, then it crashes:

 > bzr branch official PhiLho
bzr: ERROR: exceptions.AssertionError: Unable to find old fileid for 
tools/pear/PEAR.php in ('b9a71923-0436-4b27-9f14-aed3839534dd', 'trunk', 
3102)

I suppose the original repository has a SVN issue, or something unusual 
not recognized by the SVN plugin, so I thought I should expose the issue 
here. I can fill a bug if you think it is worth it.


Now, my question: actually, I don't need the whole history. I just want 
the tip of the original branch, to be able to work on my version, and to 
pull/merge new changes from the original one.
But apparently, bzr-svn kicks in when it finds a .svn directory...
Is there a way to operate on a SVN-driven directory without considering 
the whole history? Beside deactivating the SVN plugin, I mean...

Thanks.
