I've looked at this a bit.  Here's the weird part: the error says
"Uncaught Exception", but all the throws of that exception appear to be
properly wrapped in try/catch blocks.  So a simple "change exception into
an mbox" kind of solution won't work here.  More debugging is needed.

To whomever can reproduce this problem: can you please run setup under gdb
(even if you don't have a debug version -- this is just to get the log
output) and send me the *full* log output and the tarball that setup
claims to be corrupt off-list?  Once I can reproduce this, I'll try to dig
further.
