Bug#941585: python-meshio: FTBFS / autopkgtest failure on i386

Hi Maintainer

Since the upload of python-meshio 3.1.1-1, autopkgtests have been 
failing on i386 in Ubuntu with the errors below.
This also appears as a FTBFS on Debian's reproducible builds [1].

Could this test be made more tolerant?

Regards
Graham
