I am posting this to Zope Digest since the N & H people have no Bug Collector of their own on the WorldPilot site, and I don't know how to get through to them otherwise. If you know anybody who works for them, please pass this on. There is a bug in WorldPilot 1.0 release 1 that causes a re.split error if you have certain kinds of IMAP folder names, e.g. an all numeric one like "2000". The problem is that in WorldPilot.py around line 415 you have 414 for folder in FS: 415 FolderFullName=folder[2] 416 cf=rf 417 Folders=re.split(r'\.', FolderFullName) but apparently folder[2] may not be a string if the IMAP name looked un-stringlike. The following change fixes the problem and lets you work with any IMAP folder name: 415 FolderFullName=str(folder[2]) I really like the looks of WorldPilot - all it lacks to be a really killer app is a search function.
