problem2html crashing

[bandgeekdante]

I'm getting the following error message when running problem2html after updating problemtools:

Traceback (most recent call last):
  File "/usr/local/bin/problem2html", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.8/dist-packages/problemtools/problem2html.py", line 140, in main
    convert(options.problem, options)
  File "/usr/local/lib/python3.8/dist-packages/problemtools/problem2html.py", line 43, in convert
    tex = plasTeX.TeX.TeX(**{argname: texfile})
TypeError: __init__() got an unexpected keyword argument 'myfile'

I've never seen this before and it happens with all problem directories, including past contest problems that used to compile perfectly into HTML. Within verifyproblem, this shows up as

ERROR in problem statement: Could not convert problem statement to html for language "".  Run problem2html  on the problem to diagnose.

I have plasTeX version 2.1, and this problem likely comes from 5208a60

Will be fixed once there is a plastex release that includes plastex/plastex#308. (I wouldn't be opposed to a temporary problemtools workaround though, using try-catch instead of checking __version__.)
