Sure. The problem seems to be related to the brasero library, from the

Unfortunately, there are no debugging package with symbols for brasero

interferes with my package usbmount.

Yes, we should get prepared for an imminent release of testing, to have
everything working fine so that the release is not delayed after the
freeze.
