Please describe the problem:
I have a GtkFileChooserButton and I want to set a filename without opening a dialog with gtk_file_chooser_select_filename ().
When the destination directory has few files it's quick, but when the directory has a huge number of files this takes ages. 
Say for instance that I want to set the filename /usr/bin/ctags:
They're a lot here
ls -l /usr/bin/ | wc -l
3731

it seems to me that in background the call fills values/widgets etc as if I was opening it with a dialog, which is bad.
See bug #551347 for other infos.




Steps to reproduce:
1. You can try Anjuta rev 4234, with symbol-db activated.
2. Go on edit->preferences.
3. Switch to symbol-db tab and see that the 'Ctags executable' is void for a minute or more.

Expected results:


Does this happen every time?
Only when the files in the directory are many, but this bug makes the application unusable.
