lyx_mirror/src/Buffer.cpp
Vincent van Ravesteijn 0aca981637 Fix bug 5699 (crash when using outliner in child document while the master is not opened). 
The problem was that, if the master is not opened, no respective guiDelegate exists, and the functions that update the toc do not trigger. The fix is to update the child's toc backend and toc items directly in such cases.
