FWIW:  `gbp clone` does also checkout of the branches it will be needing.

Important / relevant output of `uscan --verbose`

uscan info: Launch mk-origtargz with options0:
   --package gmsh --version 4.5.2 --repack-suffix +ds1 --compression default --directory .. --copyright-file debian/copyright
   ../gmsh-4.5.2-source.tgz

   gzip: stdin: unexpected end of file

So error is indeed reproducable.

Elsewhere in the `uscan --verbose` output was download URL. I did
  wget http://gmsh.info/src/gmsh-4.5.2-source.tgz

Then a check on thoses   .tgz
```
$ ls -l gmsh-4.5.2-source.tgz ../gmsh-4.5.2-source.tgz 
-rw-r--r-- 1 gs0604 gs0604 14841817 feb  3 21:10 ../gmsh-4.5.2-source.tgz
-rw-r--r-- 1 gs0604 gs0604 14841960 jan 30 13:06 gmsh-4.5.2-source.tgz
```
Do note the difference in size.


Tests with  `mk-origtargz`:
```
gs0604@trancilo:~/src/salsa/gmsh
$ mk-origtargz --package gmsh --version 4.5.2 --repack-suffix +ds1 --compression default --directory .. --copyright-file debian/copyright ../gmsh-4.5.2-source.tgz

gzip: stdin: unexpected end of file
tar: Onverwacht einde-van-bestand in archief
tar: Error is not recoverable: exiting now
mk-origtargz: error: tar -t -a -f ../gmsh-4.5.2-source.tgz subprocess
returned exit status 2
gs0604@trancilo:~/src/salsa/gmsh
$ mk-origtargz --package gmsh --version 4.5.2 --repack-suffix +ds1 --compression default --directory .. --copyright-file debian/copyright ./gmsh-4.5.2-source.tgz
Successfully repacked gmsh-4.5.2-source.tgz as ../gmsh_4.5.2+ds1.orig.tar.xz, deleting 349 files from it.
gs0604@trancilo:~/src/salsa/gmsh
$
```

So it is the `mk-origtargz` that yields the 'gzip: stdin: unexpected end of file',
but only on the gmsh-4.5.2-source.tgz that uscan did download.



I don't have an answer on the "why?"
Neither an advice what to do with the encountered issue.
