In my application stackprinter ignores the passed in supressed_paths and I am not sure why (this has already worked and I am not sure what changed).
I can't seem to create a short snippet which reproduces the error but in my application it fails every time.
This is the function where I get the traceback.
If I set a break point with the debugger I see that suppressed_paths is indeed properly populated. However if I inspect the returned lines I see the traceback with the included library files.
I have created a testcase for pytest which fails every time.

I tried to recreate the issue with a snipped but the library files are correctly ignored here, so I am confident that my regexes are correct and that I pass in the parameters correctly.

It would be really nice if you could check out the dev branch and run pytest on the test_wrapper.py file.
The tests need the following libraries additionally to the ones in requirements.txt:
pytest pytest-asyncio asynctest
