Dear maintainer, Here is the debdiff for the NMU of a2jmidid that I sponsored, which fixes this bug. Apologies for not posting an NMU diff to the bug before making the upload.
Further apologies for not uploading to a DELAYED queue. I hadn't known that the a FTBFS on a release architecture is only of RC severity if it's a regression. Regards. -- Sean Whitton
