Nautilus bookmarks and Places problems

I rely rather heavily on the bookmarks/places sidebar in Nautilus (Gnome's file manager). I have a very large archive of freeware, evaluation software, reference material, and documents files sorted by OS and application type, category, or customer project number. It takes a lot of clicking to drill down into and the bookmarks allow me to jump quickly to the directories I use the most. I also have bookmarks to SMB shares on various subnets and across a VPN. Its worked rather well but I noticed that I couldn't sort the list the way I wanted. Normally you can just click-and-drag a bookmark and drop it where you want. But when I tried it didn't work correctly and ignored the action or replaced it with a different bookmark like it lost track of which one I was moving. I decided to resolve the problem by deleting several bookmarks I thought it could be having trouble with like the SMB shares. But it still didn't work. After some searching I figured out that the bookmarks are stored in the hidden text file ~/.gtk-bookmarks which is easy to edit manually. I found several bookmarks that Nautilus was not displaying which pointed to old targets that no longer existed. I deleted them and killed and restarted Nautilus and it seems happy now. It might be a design flaw or a bug. I'll have to investigate more after I upgrade to Gutsy.
