In my action group one action tries to import a cover from a predefined
directory, where I store cover art.
I used the following two actions w/o problems until the latest 2.48e update
With 2.48e cover import no longer works as before and as documented. The change log does not mention anything related, so i'd consider this as a bug.
Verified by downgrading: After installing 2.48d everything is working again.
