Unable to "Backup Notes"

Testing version: Version 2.5 (13604)

What were you doing: Trying to backup the whole database

What feature did you use: Backup

What happened: No backup dialog appears. Normally, I am prompted to choose a location to store the backup, but now nothing happens. Note that clicking “Restore Backup” still works (or at least displays a file selection window).

What did you expect to happen:

Please update to release 2.5.1. This bug should be fixed.
