Bug#1086548: python-meshio: autopkgtest fail in testing

[Antonio Valentino]

Source: python-meshio
Version: 7.0.0-really-5.3.5-3
Severity: normal
X-Debbugs-Cc: antonio.valentino at tiscali.it

Dear Maintainer,
autopkgtest for msh2xdmf fail in testing: see
https://ci.debian.net/packages/p/python-meshio/testing/amd64/53937343/

The issue seems to be linked to the inability to import the "dolfin"
package.

This issue is blocking for the migration of h5py to testing and,
if not solved, will cause the autoremoval of several packages from
testing.

Please find below the relevant part of the log:
