Segmentation error with pdb files:

[sgrannem]

Describe the bug
When I run plip in the command line with a specific pdb file it crashes due to a segmentation error.
I cannot really figure out where the error comes from.

To Reproduce
Steps to reproduce the behaviour:

Using a downloaded pdb file:

% plip -f 5o9z.pdb

Asking plip to download the pdb file:

Hi sgrannem,

most likely this error comes from OpenBabel. We've seen these kind of errors before. Especially when parsing large CryoEM structures. If this is true there is nothing much we can do about it. Can you split your structure before processing with PLIP and use a local file instead of letting PLIP download it?
