#1294 Autolink to file: does not work anymore

[fdar]

The "autolink to file" does not work anymore on the branch dev_2.11 .
It was working in version 2.11b3

Method:
- Open an existing database
- Select an entry (containing a valid file link)
- Go the the General tab of the entry editor
- Click on "Auto"
==> the little window "Auto define links" stays open for ages

Note:
After closing the "Auto define links" window manually:
- if only a main directory is defined (Options -> Preferences -> External programs), no file is added to the field "File".
- if the database includes a specific ganeral directory, a file is added to the field File.
