GYB 0.29: Can't restore from Gmail Takeout MBOX without stripping labels

[Notch]

I have a Gmail Takeout created MBOX that I don't seem to be able to restore due to a label creation error.  If I strip the labels then it seems to import.  But I have probably over 100 labels and preserving them and the label hierarchy are of importance.

Output:

C:\gyb>gyb --email XXXXX...@gmail.com --action restore-mbox --local-folder C:\gyb

Using backup folder C:\gyb

Restoring from C:\gyb\All_mail.mbox

Traceback (most recent call last):

Suggestions on how to further troubleshoot?  Have tried on Mac and Windows - makes no difference.  Must be an issue with one or more of the Gmail labels.  Some do contain spaces, is there maybe a quoteblock missing in the GYB code that is having issues creating new labels with spaces.  Or with nested labels.  Or nested labels with spaces.  I don't know - just guessing.

????

Thanks!

Tested with GYB 0.30 but unfortunately this bug still exists.
