[SM-PLUGINS] GPG Plugin and SM 1.5.0 -- "No available imapstream"

[Anders la C. B. <an...@be...>]

Hello,

I'm having problems getting the GPG plugin version 2.0 to work with 
SquirrelMail testing 1.5.0 on an Apache 1.3.31 server with PHP 4.3.7 and 
GnuPG 1.2.4. Maybe SM 1.5.0 simply isn't supported by this version of 
the plugin? I'd be very interested in hearing the experiences of other 
people as regards these specific versions.

More specifically, the plugin installs all right and I'm able to upload 
both public and private keys. But when I open an encrypted message and 
hit Decrypt, several warnings and errors are displayed after I enter my 
passphrase:


Warning: array_values(): The argument should be an array in 
[path-to-SM]/functions/imap_mailbox.php on line 108

ERROR:
ERROR : No available imapstream.

Warning: array_unique(): The argument should be an array in 
[path-to-SM]/functions/imap_mailbox.php on line 108

Warning: array_values(): The argument should be an array in 
[path-to-SM]/functions/imap_mailbox.php on line 108

Warning: implode(): Bad arguments. in 
[path-to-SM]/functions/imap_mailbox.php on line 681


These warnings and errors appear where SM normally displays links to 
Compose, Addresses, Folders, etc. Underneath the last warning, the 
message view appears as it normally would, displaying the headers of the 
message as well as the message itself -- and it is actually decrypted.

I have SM 1.4.3a running concurrently on the same server, and the GPG 
plugin works flawlessly there. This leads me to believe that the problem 
resides in the interaction between SM 1.5.0 and the GPG plugin; what can 
I do to get it to work with SM 1.5.0? Would it take major changes? At 
any rate, I hope someone can benefit from my ramblings.
