No; the error is in the libsvn_fs libraries, which is roughly the
opposite end of the world relative to libsvn_wc's entries files...
(and I bet the error will reproduce even with 'svn mkdir URL', which
doesn't involve an entries file at all)

When the error occurs, fs_fs.c is reading a node-revision header from
some file; and that header is corrupt. I asked you to look in *that*
file (it will be somewhere under /var/run/svn/db/) and see in what way
it is corrupted. For example, what is the value of read_rep_offsets()'s
second parameter?

For reference, read_rep_offsets() --- the function where that error
occurs --- is the function that parses the "text:" line in the
following:

[[[
id: c-1.0.r1/998
type: file
count: 0
text: 1 106 44 32 8ac35a19435b31b928de300b32e930cd b3f85be4422626e7443b6ddcf60bb451dc7f0560 0-0/_e
cpath: /trunk/A/B/E/alpha
copyroot: 0 /
]]]

so the second parameter is expected to contain the "1 106 ... 0-0/_e" string.
