When profile editor is used in Zenmap 7.90 (multiplatform), Zenmap tends to crash with a traceback like:

Version: 7.90
Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/zenmapGUI/ScriptInterface.py",
line 261, in script_list_timer_callback
callback(True, process)

line 270, in initial_script_list_cb
if status and self.handle_initial_script_list_output(process):

basename = os.path.basename(filename)
NameError: global name 'os' is not defined

This was actually caused by "improvements" we made as part of our recent LGTM code quality efforts. We removed a bunch of "from X import *" statements for various libraries because those can pollute the namespace by importing way more than intended. But it turns out we were relying on one of those secondary imports then importing "os" itself. So we should fix this and also try to make sure there aren't other cases of this problem that we missed.
