:I don't think that it likes that MutexFile.MutexFile object in user. Try
:pulling it out of there and putting it somewhere else in the code.

I don't think that is the problem, because before I introduced the user
class, I was running this code without any problem (this is only a
snippet of the code, of course):

class mssgBoard:
    def __init__(self, dict=None, caller=None):
        self.lockfile = MutexFile.MutexFile('main.lck')
        self.myfilename = 'mainboard'
        if caller == 'init':
            try:
                self.lockfile.flock('LOCK_EX')
                db = shelve.open(self.myfilename, 'n')
                db['title'] = dict['title'].value
                db['adminID'] = dict['adminID'].value
                db['smtpserver'] = dict['smtpserver'].value
                db['exitURL'] = dict['exitURL'].value
                db['adminEmail'] = dict['email'].value
                db['threads'] = []
                db.close()
                self.lockfile.flock('LOCK_UN')
            except KeyError, e:
                print header('Error in Message Board Init')
                print body('missing keys')

Notice that it also has a MutexFile object, and it caused no problems in
shelving that object.

Code runs fine when I comment out the addUser function and the call to
it.
