+Yes, the file gst-plugins-good-0.10.26.tar.bz2 had been removed from the
+binrepos SVN (so it was not imported on the new binrepo), but for some
+reason was not removed from sha1.lst. The previous version of mgarepo
+did not make an error when a file was listed in sha1.lst but was not in
+the binrepos SVN, so this kind of problem in sha1.lst was not noticed.
