UnboundLocalError in parser.py

[jkeaton]

Line 249 of file lesscpy/lesscpy/lessc/parser.py as of commit 295afcf raises UnboundLocalError when none of the 3 conditions above it are met. Changing lines 239-249 to the following would fix it:

ipath = fe = None
if isinstance(p[3], str):
    ipath = utility.destring(p[3])
elif isinstance(p[3], list):
    p[3] = Import(p[3], p.lineno(4)).parse(self.scope)
    ipath = utility.destring(p[3])
elif isinstance(p[3], Call):
    # NOTE(saschpe): Always in the form of 'url("...");', so parse it
    # and retrieve the inner css_string. This whole func is messy.
    p[3] = p[3].parse(self.scope)  # Store it as string, Statement.fmt expects it.
    ipath = utility.destring(p[3][4:-1])
else:
    ipath = utility.destring(str(p[3]))
fn, fe = os.path.splitext(ipath)
