I cannot reproduce the problem. Locally, I can use gdb for remote
buffers without problems, and I see the source buffer.
Do you have some special settings one should care? I simple scenario I
could follow?

Hmm. That's kind of caching Tramp uses internally. Hard to debug, I confess.
The idea is that tramp-get-file-property is called first, which shall
return the cached value. Only in case it returns 'undef, the body of
with-file-property is evaluated, and the result is put into the cache via
tramp-set-file-property.
