In reply to buzby:
You wont stop the crack growing with tape or glue, if it wants to keep going it will. The tape will at best keep the weather out (as will the intact inner glass) and the glass in place if it splinters (unlikely). If you want to stop the crack could drill out the ends of it but there's a fair chance it won't work and the tools would probably cost more than a new pane of glass.
Personally given it's going in spring anyway I'd pretend it never happened and leave it alone.
