If a regular expression ends with a backslash, an exception is raised. Of course, the backslash has to be escaped. The simplest example, that causes the error is a regular expression, that should match only a single backslash:
import re
r = re.compile("\\")

You either have to double escape it (once for python and then for the regex engine) or use raw strings:
>>> re.match("\\\\", '\\').group()
'\\'
>>> re.match(r"\\", '\\').group()
'\\'
