Yes, it is. Here's a php script I used once to fix broken files.

<?php

$file    = $_SERVER['argv'][1];
$content = file_get_contents($file);
$header  = substr($content, 0, strpos($content, "\r\n\r\n"));

if (!preg_match('/X-Kolab-Type: application\/x-vnd\.kolab\.file/',
$header)) {
    echo "Not a file object: $file!\n";
    exit(1);
}
if (!preg_match('/boundary="([a-z0-9=_]+)"/', $header, $m)) {
    echo "Boundary not found in file $file!\n";
    exit(1);
}

$separator = "--" . $m[1];
$content   = explode($separator, $content);
$end_part  = array_pop($content);
$file_part = array_pop($content);

list($headers, $file_part) = explode("\r\n\r\n", $file_part);

// sanity check
if (!preg_match('/Content-Transfer-Encoding: base64/i', $headers)) {
    echo "Malformed message [1]?!\n";
    exit(1);
}
if (!preg_match('/Content-Disposition: attachment/i', $headers)) {
    echo "Malformed message [2]?!\n";
    exit(1);
}

if (preg_match('/[\s\t]size=/', $headers)) {
    // size parameter already exists
    exit;
}

// calculate size
$decoded = base64_decode($file_part);
$size    = strlen($decoded);
unset($decoded);

if (!$size) {
    // error or empty file
    exit;
}

$headers = rtrim($headers) . ";\r\n size=$size";

// build the message back
$content = implode($content, $separator);
$content .= $separator . "\r\n";
$content .= ltrim($headers) . "\r\n\r\n";
$content .= $file_part . "\r\n\r\n";
$content .= $separator . $end_part;

// overwrite the file with new content
file_put_contents($file, $content);

?>

After executing it on every file in imap folder, you'd need to do the
mailbox/folder reconstruct and clear the Roundcube cache (kolab_cache_file).
