Subversion unpredictably changes file permissions

I have a sporadic problem with subversion that is driving me absolutely
insane: committing a revision can cause the permissions of the underlying
file to be changed.
I cannot predict when such behavior will occur. Everything will be fine for
several commits, and, one fine moment, even though I have not changed the
permissions in the underlying file, the commit will cause these permissions
to change. It looks like this:

% ls -l path/to/some/file
-rw-r--r-- 1 jones jones 7653 2009-02-20 21:39 path/to/some/file
% svn ci -m '' /path/to/some/file
Sending path/to/some/file
Transmitting file data .
Committed revision 1177.
% ls -l path/to/some/file
-rw------- 1 jones jones 7653 2009-02-23 13:38 path/to/some/file

To make matters worse, even if I change the permissions back to what they
were before the commit, every subsequent commit will change them back to the
unwanted value. Grrrr!!!

FWIW, at the moment I'm the only person making changes to these files
(though other uses check them out for viewing the source code).

Is there some way to tell subversion to leave the permissions alone??

Is this insane behavior documented anywhere?

This behavior is totally unpredictable (by me at least), so I cannot provide
a reproducible example.

TIA!
