tshark crashes on cleanup

I'm having wireshark 3.4.2.

And I have following error:

same err！

[BMWE]

same err！

seems that the package in pypi is not updated one. I've downloaded the src from github and compared with pypi. After updating the files, it seems to work fine.

@KimiNewt , I think that you have to update the pypi with the updated package.

But I have another problem after updating

lxml.etree.XMLSyntaxError: Input is not proper UTF-8, indicate encoding !

It seems to be the problem, that the incoming data (in XML format) is not encoded the right way and pyshark does not cast to 'UTF-8'. While debugging it posed that it appeared to be in 'latin-1'. added following line between line 26 + 27 in src\pyshark\tshark\tshark_xml.py:

xml_pkt = xml_pkt.decode('latin-1')

It worked.

Looks to be a duplicate of issue #116. Created pull request #479 for a fix.
