Could not create temporary files for Latex plugin (for no real reason)
- plugin self-test (in the edit->plugins menu) says everything is OK, but no result is shown
- in the chat window, the message in the summary appears instead of the pic with the required formulas
- when manually executing the code that does the mistake, I see that the temporary files/directories are being created, all OK, but: the line "tmpfd.close()" returns an error, because in both python3 and python2 tmpfd is an int (checked with "type(tmpfd)"), and not a file descriptor, hence it has no attribute "close()".
- the error above calls the Exception and makes the line appear
OS: Arch Linux, i386, python3 as default, but python2 available as /usr/bin/python2
