Annoying error

I have an annoying error sometimes when I restart mod_perl. It is actually on Forum pages but where I am pulling the category menu in from Links. The error is

Can't call method "table" on an undefined value at /path to admin/Links/Table/Category.pm line 44

It seems to be that $DB isn't being initialised properly. After this error, it works fine. Doesn't happen everytime, so I guess it must be where the forum page is shown before any Links pages have been shown.

Any ideas how I can stop it from happening?

I also had some similar problems with Links::Table::Category and $DB object, in Links SQL v2.2.1.

I found that this code caused me the problems in Links.pm/sub init:

Code:
    if ($DB and not ref $DB eq 'GT::Delay') { # $DB is already a GT::SQL object 
        $DB = GT::SQL->new({ 
            def_path => $CFG->{admin_root_path} . '/defs', 
            cache => 1, 
            debug => $debug 
        }); 
    } 
    else { 
        $DB = GT::Delay( 
            'GT::SQL', 'HASH', 
            { 
                def_path => $CFG->{admin_root_path} . '/defs', 
                cache => 1, 
                debug => $debug 
            } 
        ); 
    }

It happened, that $DB got somehow into the "else" condition leaf, causing to create an empty $DB object.
Note, if you compare Links.pm in v2.1.2 and Links.pm in v2.2.1, you will see that there was quite a few changes, including the code above...

However I did not investigate furthermore, what the problem really was...
Just FYI.

Thanks for replying - that gives me somewhere to start investigating.
