Please describe the problem:
When having remote locations in the nautilus bookmark list, gnome-screenshot
asks for all remote passwords upon starting. This is really annoying, as 10
bookmarks means typing in 10 passwords... clicking on "Cancel" in the password
dialog brings up the dialog another 4 times (5 times in total) for each bookmark.

This is absolutely similar in behavior as Bug 319532, which had the same issue
with the gtk-filechooser. As the gtk-filechooser bug is fixed now while the
screenshot isn't, I guess it's copy-pasted code or something.

Steps to reproduce:
1. Log into remote location in nautilus, don't save the password (e.g.
"ssh://myhost/myfolder")
2. Create a bookmark of current location
3. Start gnome-screenshot


Actual results:
You get asked for the password to all remote locations in your bookmarks list.
If you saved the password earlier, you only get asked if you want to allow
access to the passwords for gnome-screenshot, which is annoying nonetheless.

Expected results:
Like the gtk-filechooser bugfix, the application should NOT ask for all the
passwords.

Does this happen every time?
Yes
