have you tried strace -e open -ff -ofile.log ?
(it is easy to miss something in the strace output & and with -ff you
also get subprocesses (in their own files, file.log.pid1,
file.log.pid2,...)

this however, does not really look like a python problem, as from the
look of it it misses some external executable it tries to Popen()

so, you should probably on some linuxcnc/camview-emc related mailling
list/forum.

ps: a more descriptive subject line would be helpfull for people to
recognize what your post is about and then can quickly decide if they
want to look at it or not.
