To what does the word "this" refer? To the dbmopen function, somehow,
for that was the whole of the subject line? Or to the code which
follows? Or both?

No; that code will evaluate the "name" of an array in a scalar
context, storing the number of elements in the array into the hash.

Is there a reason you're keeping the error message text, and your
actual code, secret from us? If we saw those things, we might be able
to help.

A lot depends upon what you're really trying to do, and I can only
guess at that. But if you want to use a dbm file as the underlying
data structure, you shouldn't store a reference into it; maybe you
want to use join and split:
# Store a list of items into a single hash slot
$dbm_hash{$key} = join "\0", @data_items;
Elsewhere....
# Extract the list of items to an array
my @extracted_items = split /\0/, $dbm_hash{$key};
Hope this helps!
