[horde] IMAP folder problem (Horde 3.0.4/IMP 4.0.3)

[Gabriel O'Brien]

Hi folks,

I'm working on migrating from Horde 2.2 to Horde 3.0 but I've come 
across a problem that is a bit of a showstopper and I'm hoping somebody 
can explain to me why I'm stupid. ;)  Essentially it boils down to the 
fact that users can't see their IMAP folders (other than INBOX) when 
they log in to IMP 4.0.  I've played around with it, everything from 
running the upgrade scripts, etc. a dozen times to a completely fresh 
install including a new database but had no luck whatsoever, other than 
a brief period after installing from scratch where I was able to view 
the folders, but this morning when I logged in to double check 
everything they were gone again.  I've tried digging through the 
"horde_prefs" table to see if there's anything awry but the 
"expanded_folders" (which I understand to be the relevant entry) is just 
gobbledy-gook to me: a:1:{s:5:"INBOX";b:1;} . :(

I'm wondering if somebody can point me in the direction of some 
debugging hints?  I can understand that there are some problems in the 
upgrade, it happens, but I would think that a completely fresh database 
should work predictably.  I'm using uw-imapd and all user folders are 
located at ~/.imap/, it worked fine in Horde 2/IMP 3, so I'm sure I'm 
just doing something dumb like leaving out a step in the install but for 
the life of me I can't figure it out!  Let me know if I should be 
posting this to the IMP list instead.

Thanks for your help!

-Gabe
