I did some more investigation into this and committed a workaround
which avoids the problematic case [1]. I didn't have time to dig
really into the main problem, though. I'd prefer to understand the zgz
problem before uploading this.

That's a regression in the version 1.40 of pristine-tar (during the
commit).  It's almost surely due to
https://anonscm.debian.org/cgit/collab-maint/pristine-tar.git/commit/?id=0743dd36ed90c18982a5a861f4978080c1c4a2e3.

Here is what 1.39 executes during commit:

zgz -9 --original-name dist/planetfilter-0.7.4.tar --osflag 255 -T 
1501972711 -c

And here is what 1.40 does:

zgz --gnu -9 -T 1501972711

(these can obtained if you use -v switch to pristine-tar).
Extraction works fine in both cases, assuming the file was committed using 1.39.

CCing Lennart. Lennart, could you investigate?

I confirm the issue. At first, I thought it's due to the new delta
format, but then verified it reproduces with the previous format as well.

The problem seems to lay in the "zgz" utility which incorrectly
rebuilds the file, e.g., the file size does not match. It seems harder
than I expected, will have to investigate more.
