Description nzqr 2012-05-30 13:18:15 UTC 
Everything that uses caps plugin ends with double-free on exiting, i had attached backtraces for media-libs/ladspa-sdk::listplugins and aplay.

Reproducible: Always

Doesn't perform the bad delete

Prevents double-free when running listplugins. Don't know if it's a proper fix.
