I don't think that matters. Debian is happy to distribute non-copyleft
works like BSD-licensed code, which have the same potential problem.

I guess you're right.

That's a general problem with the GNU FDL: No one but the copyright
holder can copy material between a GNU GPLed program and its GNU FDL
manual. But that's a different problem than the incompatibility with
debian's definition of free software.
