Assertion failed in libsvn_subr/path.c:273 with svn update

From: Øyvind A. Holm <sunny_at_sunbase.org>
Date: 2004-07-05 11:21:26 CEST

When running svn update, svn sometimes aborts with an assertion failure:

svn: subversion/libsvn_subr/path.c:273: svn_path_add_component: Assertion `is_canonical (path->data, path->len)' failed.

It happens on almost all my svn WCs from collab.net, some of them are
locally modified, but it also happens on unmodified WCs, for example
trunk.clean which I do not touch.

This is a session from an update I just had, the WC was originally from
r10131:

I first experienced this with r10136, but it also happens with r10140 which is my current running version.

All the updates here was executed with strace, and the strace files generated can be found in
