Improve the error message "There was an error"
gtk_label_set_markup (GTK_LABEL (label_status), _("There was an error")); in
on_transfer_error. The user doesn't know which error occured (authentication, transmission, timeout, runtime, etc.) what was the reason for it and what to do to fix the issue.
I'm not seeking support in this matter, my intention is to improve the software - and frankly avoid that any user of any software ever has to face an error message of this kind.
