unable to acces Inbox

["Russell L. Harris" <rlharris hal-pc org>]

I'm running Debian "unstable" with the Gnome desktop.  I just executed  
"aptitude dist-upgrade", which leaves me running balsa 2.0.17.

In the process of the upgrade, the Inbox was re-set to /var/spool/mail/ 
rlh/ ; before the upgrade, the Inbox was /var/mail/rlh/ .

By right-clicking on "Inbox" and selecting properties, I opened the  
"Mailbox configurator" dialogue box, changed the path, and clicked the  
UPGRADE button.  But the roughly 250 messages (all of which have been  
read) no longer are displayed in the Inbox.  How can I access these  
messages?
