Bug#1118028: qutip: TestBosonicEnvironment test_fixed_prony_fit fails tolerance with generic netlib BLAS

[Drew Parsons]

Source: qutip
Version: 5.2.1-2
Severity: serious
Justification: debci
Control: forwarded -1 https://github.com/qutip/qutip/issues/2758

test_fixed_prony_fit in TestBosonicEnvironment
(tests/core/test_environment.py) is failing to meet tolerance with
qutip 5.2.1

The problem is triggered by generic (netlib) BLAS.
The test passes with optimised BLAS (e.g. OpenBLAS)

Upstream is preparing a patch
