mail-notification is unable to retrieve passwords when keyring database name contains diacritics

[Bunio_FH]

In polish default database name is "Domyślna" which causes gnome-keyring daemon to identify dbus paths as (dbus-monitor dump) in example:

method return sender=:1.3 -> dest=:1.166 reply_serial=5
   array [
      object path "/org/freedesktop/secrets/collection/domy_c5_9blna/3"
   ]
   array [
   ]

then GetSecrets is called:

method call sender=:1.166 -> dest=org.freedesktop.secrets serial=15 path=/org/freedesktop/secrets; interface=org.freedesktop.Secret.Service; member=GetSecrets
   array [
      object path "/org/freedesktop/secrets/collection/domy_c5_9blna/3"
   ]
   object path "/org/freedesktop/secrets/session/s13"

which receives a proper response (***), but right after that it tries to obtain dbus properties with a wrong path:

method call sender=:1.166 -> dest=org.freedesktop.secrets serial=20 path=/org/freedesktop/secrets/collection/domy_ffffffc5_ffffff9blna/3; interface=org.freedesktop.DBus.Properties; member=Get
   string "org.freedesktop.Secret.Item"
   string "Attributes"

which of course is met with:

error sender=:1.3 -> dest=:1.166 error_name=org.freedesktop.Secret.Error.NoSuchObject reply_serial=20
   string "The '/org/freedesktop/secrets/collection/domy_ffffffc5_ffffff9blna/3' object does not exist"

this causes mail-notification to be unable to save passwords and causes it to ask for a password every time it tries to check the e-mail. I came up with a quick workaround which is changing the actual path to the database:

killall -9 gnome-keyring-daemon mail-notification
mv ~/.gnome2/keyrings/$(cat ~/.gnome2/keyrings/default).keyring ~/.gnome2/keyrings/default.keyring
echo -n "default" > ~/.gnome2/keyrings/default
mail-notification &
