Summary: segmentation fault on mailstorage_connect()

Initial Comment:
Hi. 

I've got a reproducable crash with example program frm-tree

It seems to crash when doing:
  ./frm-tree --driver=pop

It doesn't seem to matter if I give it the server
hostname, port, username, or whatever.

It works with imap driver.


$ gdb

(gdb) file frm-tree
Reading symbols from frm-tree...done.
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) run --driver=pop
Starting program:
/local/src/libetpan-0.32/tests/frm-tree --driver=pop

After more testing, it seems to crash with the same error if
you try to use a nonexisting driver.

With more debugging, it seems to try to access local mail
folders if you give it a nonexisting driver:

<<<
(gdb) print storage
$1 = (struct mailstorage *) 0x804a308
(gdb) print storage[0]
$2 = {sto_id = 0x0, sto_data = 0x0, sto_session = 0x0,
sto_driver = 0x0, sto_shared_folders = 0x804a328,
sto_user_data = 0x0}
(gdb) print storage[0]
$3 = {sto_id = 0x0, sto_data = 0x0, sto_session = 0x0,
sto_driver = 0x0, sto_shared_folders = 0x804a328,
sto_user_data = 0x0}
(gdb) print storage[1]
$4 = {sto_id = 0x0, sto_data = 0x11, sto_session = 0x0,
sto_driver = 0x0, sto_shared_folders = 0x0, sto_user_data =
0x31}
(gdb) print storage[2]
$5 = {sto_id = 0x804a368 "/var/mail/twillber", sto_data =
0x0, sto_session = 0x804a308, sto_driver = 0x0,
sto_shared_folders = 0x0,
  sto_user_data = 0x0}
>>>

The $5 suggests it tries to use local mail.
I think it would be wise to give the user an error instead
of using some hardcoded default driver.

I actually tried to test pop3-functionality in first place... :)
