imap folders wrong prefix

[glen]

i encountered rather odd problem when upgraded from 0.5-beta to 0.5-rc

i seem to be no longer see private folders starting with s* (altho one private folder i can access), it says:
"Server Error: SELECT Mailbox does not exist, or must be subscribed to."

config part:

$rcmail_config['imap_ns_personal'] = null;
$rcmail_config['imap_ns_other']    = null;
$rcmail_config['imap_ns_shared']   = null;

or even if i force ns:

$rcmail_config['imap_ns_personal'] = 'INBOX.';
$rcmail_config['imap_ns_other']    = null;
$rcmail_config['imap_ns_shared']   = 'shared.';

in the picture :
...

• pld OK
• servers FAIL
• shared (shared folder top dir) OK
• Spam OK
• subscriptions FAIL
• svn FAIL
• trash FAIL

if i used C locale sorting, the Spam would be before "shared", so "shared" namespace corrupts all other private folders?

for "subscriptions" folder i enabled imap log and it shows:

yet for "pld" imap log is with correct prefix:

something went wrong with mixing shared and private namespaces?

[thomasb]

Duplicate or at least related to #1487649

[glen]

i can confirm [1c7b94b5] fixes it for me too, so #1487649 was duplicate :)

< STATUS INBOX.* go on... then logout >

With manual imaps session via openssl, "SELECT INBOX" works fine

[alec]

This patch should fix your issue, but I'm not sure if this doesn't break something for others. However, there should be only one INBOX, so maybe this is a right way.

Better solution is propsed in #1487637.

[janisk]

thanks, this works in my case and folders are accessed/manipulated correctly.
