hgtk hangs when navigating to revision -1 (000000...)
I just converted an SVN repository that had two branches. In Mercurial repository one has the changeset 0 as the parent. The other one has revision -1 (000...) as the parent. When clicking on the zeros hyperlink (0000...) in Repository Explorer the hgtk hangs and knocks the processor high up. The link is displayed in the lower right window that displays changesets.
