Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@conda-forge/core I'm facing a peculiar problem here:

Somehow the tests fail on Windows: when trying to import Qscintilla with:

import PyQt5.Qsci

it fails with

ImportError: DLL load failed: The specified module could not be found.

I opened the Qsci.pyd in a dependency tracker and found the following:

Apparently the module is trying to find the required DLLs with _conda suffixes, while they are all present in Library\bin without the suffixes. Is this a setting in my recipe or build scripts somewhere that causes the Qsci module to add these suffixes in its lookups?

The previous builds of Qscintilla2 also have this problem and are thus effectively broken...
