When adding a new usual graph from the template on a filtered .g6 file, the software adds to the combobox 2 items:

• an empty graph
• the actual graph the person created

When clicking on the blank graph, the software throws an error and adds the label "Invalid Graph" to it.

Investigating, it was discovered that the filtered .g6 file has a final line break, and when adding another graph, the blank line is kept, thus creating the invalid graph.

Note
This problem is related to the issue solved on #397
