Seems at line 101 of imp/lib/Search.php it does a foreach over the results
of _getVFolderList().  _getVFolderList() says:

if ( empty($vfolder)) {
     retun $vfolder;
}

This can return a non-array value (if such is passed in) and hence can
cause the foreach to bomb.  I see the following in the logs which lead
me to this:

Jan 18 21:15:52 web2 httpd: PHP Warning:  Invalid argument supplied  
for foreach() in /httpd/horde/imp/lib/Search.php on line 101
Jan 18 21:17:27 web2 httpd: PHP Notice:  Undefined index:  folders in  
/httpd/horde/imp/lib/Message.php on line 625

Not sure why this would happen, or how to fix it, or if any of the above
conclusions are even correct...
