inconsistent sub-folder information in mail store

[Stephen Ingram]

One account on the server includes a folder called CLIENTS which
contains server sub-folders. Today, all of these sub-folders are no
longer visible in the imap client (Thunderbird). Checking the server
itself, the sub-folders are still there along with all of the mail.

cyradm reports: user.jmaxwell.CLIENTS (\Has no children) when issuing
lm user.jmaxwell.*

although when issuing lm user.jmaxwell.CLIENTS.*, all of the
sub-folders are visible.

I've tried a reconstruct on both the full user mailbox: reconstruct -r
-f user.jmaxwell, and the folder itself reconstruct -r -f
user.jmaxwell.CLIENTS. When the reconstruct is performed on
user.jmaxwell, the CLIENTS subfolders don't appear in the results.
However, when the reconstruct is performed on the
user.jmaxwell.CLIENTS folder, all of the sub-folders appear in the
results.

I'm guessing this means that the index inside of the CLIENTS folder is
corrupted. Is there a way to fix this alone?

I'm running the invoca 2.4.13 rpms on CentOS 5.3.
