[Beaver-devel] Segfault

[Double 12]

This segfault is a bit hard to reproduce.
It happens when you do the following:

1. Create a new file and leave it empty
2. Save the empty file as the first file in a hidden (.directory) directory

I looked a bit at it and found that it is caused in the line notebook_add_page(filename) in the function save_file_as.
I put some printf debug lines in the function notebook_add_page to look up the error, but now the error is not reproducable anymore.
