It is not a bug in Python; please look at the description of the
intern builtin to see why that happens (perhaps the raise/try
specification also requiring on using identical, not equal strings).

Anyway, the neat trick is to write

problemWithBlank = "Problem with blank"

def raiseProblemWithBlank():
    raise problemWithBlank

def test4():
    try:
        raiseProblemWithBlank()
    except problemWithBlank:
        print "Test4: No Problem with blank" # does not work :-(

test4()

Please note that string exceptions are deprecated; the Pythonic way to
write this code is

class ProblemWithBlank(Exception):
    pass

def raiseProblemWithBlank():
    raise ProblemWithBlank

def test4():
    try:
        raiseProblemWithBlank()
    except ProblemWithBlank:
        print "Test4: No Problem with blank" # does not work :-(

test4()
