Description of Problem:

If your mail account name contains a forward 
slash character, the folder bar incorrectly 
displays bolded texts "Summary" for each and 
every folder, instead of the actual folder 
names, and will not allow you to access a 
folder in this account.

This behavior was observed both with an IMAP 
and a Connector/Exchange account.

Steps to reproduce the problem:

1. Make sure you have the menu selection View 
-> Folder Bar enabled.
2. Create or modify a mail account by 
selecting Tools -> Mail Settings... from the 
menu.
3. In the Account Information and Name field, 
type e.g. "John Smith / ACME", and click the 
OK button to save your changes.
3. Restart Evolution and look at the folder 
bar. Try to click on one of the 'folders' in 
this mail account.

Actual Results:

Evolution displays the folder hierarchy fine 
(i.e. folders are expandable if they 
contain subfolders), but instead of the 
actual folder names, it just displays 
"Summary". Clicking on one of the folders 
will perform no action whatsoever.

Expected Results:

Obvious. Folder bar should display names such 
as Inbox, Outbox, etc. instead of the text 
"Summary" for each folder. Clicking on a 
folder should display its contents.

How often does this happen? 

Every time.

Additional Information:

Although this problem is very easy to work 
around (remove the slash from the mail 
account name), finding out what was causing 
the problem was a very laborous task. After 
all, who might have guessed such a simple 
thing as the mail account name would render 
you practically unable to access your mail 
server with Evolution?

Presumably this same problem could be 
reproduced using some other "special" 
character than the forward slash.
