Saving attachment displays error because of null path

[Jonathan Reed]

When attempting to save an attachment in Evolution 3.2.3-0ubuntu6 on a clean install, saving the attachment opens a GtkFileChooser initially browsing the path "", which naturally displays an error saying "The folder contents could not be displayed: Operation not supported". This is because the key Gconf key "/apps/evolution/shell/file_chooser_folder" is set to an empty value. If set to the user's homedir (e.g. file:///home/joeuser), or even a sane default (e.g. file:///), this error is not displayed. If the user dismisses the error, and navigates to a valid location in the GtkFileChooser and saves the file, then that location will be saved in the Gconf key and the error won't recur, but this is not good user experience.

Steps to reproduce on a clean install of Ubuntu 12.04:

1) Launch Evolution.

2) Configure an e-mail account.

3) Navigate to a message with an attachment

4) Attempt to save the attachment

5) See the error.

6) Run gconftool-2 -s /apps/evolution/shell/file_chooser_folder -t string "file://$HOME"

7) Repeat steps 1-4, note that no error occurs.
