strip: access bookmark before getting a reference to changelog Bookmark access might invalidate the current changelog (to make sure both are in a reasonable synchronisation state). So we should grab the reference to changelog after we access bookmark. Otherwise we risk using a dead object for the whole strip process. (note: this dead object business probably requires a new layers of checking)
