Problem with <mark all as read> menu

[grape6]

1. when try to mark all messages in folder as read by in drop down menu,
   i've got an error:

C: A0004 UID STORE INVALID +FLAGS.SILENT (\Seen)
S: A0004 BAD Error in IMAP command UID STORE: Invalid uidset (0.001 + 0.000 secs).

appears after commit "Fix possible IMAP command injection and type juggling vulnerabilities (#6229)"

2. if we have unread messages in more than one folder, pressing in drop down menu
   has no effect.

Fixed issue 1. Could you describe the second issue in more detail? Which drop down menu? Are you talking about multi-folder search result or what?

[grape6]

sorry, missed some details.
right click on folder name -> drop down menu -> select .
if only one folder has unread mails - pressing MARK works as expected.
if more than one folder has unread mails - pressing MARK has no effect.

Fixed.
