Package: mypaint
Version: 2.0.1-13
Severity: important
Dear Maintainer,
Launching MyPaint under testing leads to the following backtrace without any
action from the user:
----------8<----------
~$ mypaint
INFO: mypaint: Installation layout: conventional POSIX-like structure with
prefix '/usr'

_ZDATA_ONES = zlib.compress(np.ones((N, N), 'uint8').tostring())
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'numpy.ndarray' object has no attribute 'tostring'
---------->8----------
The reason is that numpy.ndarray.tostring(...) has been deprecated in numpy 1.9
and removed in 2.3.
2 commits already exist upstream to move to the new API of numpy:
*
https://github.com/mypaint/mypaint/commit/2a92b6baf452aba2cff3cc0a7782b301da3933d7
*
https://github.com/mypaint/mypaint/commit/ab017e073e83a4930a0fb09608682bf4b7ab1874
AFAICT, those 2 commits seems to be enough to fix the problem.
best regards
Rémi
