svn errors updating ports tree

[Anton Shterenlikht]

In the last few days I'm having these svn error:

svn: E185002: Svndiff has backwards-sliding source views

or

svn: E185005: Decompression of svndiff data failed: no size

when updating the ports src tree on ia64 -current.

I then run "svn cleanup", but the following svn up
again shows one of the above errors.

What's going on?

I use subversion-1.8.8_2 and
https://svn0.eu.freebsd.org/ports/head

Please advise

Thanks

Anton
