mutt somehow stopped tracking new mails. Fortunately
:set check_mbox_size on works around that.My subversion working copy from openSUSE was created with svn 1.5 but Hardy has only 1.4. So I manually got debs from the coming Intrepid release, and luckily 3 of them were enough:
dpkg -i {subversion,libsvn1,libneon27-gnutls}*.deb from here and here.
