This is a subversion issue, not TSVN, so you should ask on the
subversion users mailing list.

Subversion cannot merge changes in binary files, unless Visio itself can
do it and you specify it as a merge program in TSVN's settings. Normally
you would set the svn:needs-lock property on binary files, which makes
them read-only in your working copy, unless you take out a lock on the file.

If visio is holding the file open, there is not much that can be done to
update your working copy, although Subversion could probably fail more
gracefully when this happens. I believe there is a subversion issue open
for this, and possibly a fix on trunk.
