[Developers] "Can't locate this clause - cannot continue" error

[Philip Kendall]

While playing around with some things on sandbox, I'm occasionally
getting a "Can't locate this clause - cannot continue" error for one in
a large number of basically identical writes that I'm performing. The
(Perlified) response is below, with vague apologies for the formatting:

$VAR1 = {
          'transaction_id' => 'cache;cache01.sandbox.sjc1:8101;2008-09-23T21:30:02Z;0003',
          'query' => {
                       'messages' => [
                                       {
                                         'info' => {},
                                         'query' => {
                                                      'error_inside' => '.',
                                                      'type' => '/user/pak21/default_domain/zx_spectrum_game',
                                                      'guid' => '#9202a8c04000641f8000000004f9c3fc',
                                                      'wos_id' => {
                                                                    'value' => 167,
                                                                    'connect' => 'update'
                                                                  }
                                                    },
                                         'path' => '',
                                         'code' => '/api/status/error/mql/result',
                                         'message' => 'Can\'t locate this clause - cannot continue'
                                       }
                                     ],
                       'code' => '/api/status/error'
                     },
          'status' => '200 OK',
          'code' => '/api/status/ok'
        };

Is this a bug, or something I'm doing wrong?

Cheers,

Phil
