Thanks for the report, I'll try to have a look later this week

BTW, can you provide details (link, source code) on the plugin causing this issue ?

Hi dregad,

The plugin causing this issue is an internal plugin.
It allows our users to filter on the project of related issues.
So on a filter, we have to join relationship table and bug table.

$t_query = array(
'join' => "LEFT JOIN mantis_bug_relationship_table prt ON prt.source_bug_id = mantis_bug_table.id
LEFT JOIN mantis_bug_table pbt ON prt.destination_bug_id = pbt.id",
'where' => "pbt.project_id IN ( $t_prod_allo_ids ) AND prt.relationship_type = $t_rel"
);
