[Python-modules-team] Bug#926351: python3-tesserocr: segfaults on import

[IOhannes m zmoelnig]

Package: python3-tesserocr
Version: 2.4.0-4
Severity: grave
Justification: renders package unusable

Dear Maintainer,

i'm experimenting a bit with OCR and tried out python3-tesserocr.
Unfortunately, it appears to be completely unusable:

~~~
$ python3
Python 3.7.3 (default, Mar 26 2019, 07:25:18) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tesserocr
!strcmp(locale, "C"):Error:Assert failed:in file baseapi.cpp, line 209
Segmentation fault (core dumped)
$
~~~

my locale setting uses 'C.UTF-8', but when i tried to set other values i get the
same result:

~~~
$ LANG=de python3
Python 3.7.3 (default, Mar 26 2019, 07:25:18) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tesserocr
!strcmp(locale, "C"):Error:Assert failed:in file baseapi.cpp, line 209
Segmentation fault (core dumped)
$
~~~

Since I see no way to use this package when even importing fails with a
segfault, i use severity 'grave'.
Hopefully this package will be fixed.
