I have a problem when deleting a project. If this project has one or more bugs listed and I want to delete this project, I get an System Notice "Undefined offset: 1". Inline messges must be enabled in config_inc.php. I could narrow down the cause of this Message. It is in config_api.php in line 108:

Code:
list( $t_type, $t_raw_value ) = explode( ';', $t_value, 2 );

It seems, that the cache variables exist, but they are all empty. The project is deleted after that, but I get this notice.

Is this a known issue or is there something wrong with my installation (Mantis 1.0.7)?
