Web fails with import exception

[jamoore]

After starting web, I browsed to localhost:8000 and got the following:

Traceback (most recent call last):

Ola, this comes from the re-working of the python imports. Adding "import omero_ServerErrors_ice" or "import omero.clients" at the appropriate spot would solve the problem.

Josh, I cannot reproduce it on my machine. Could you please make a clean and see if it helps?

[jmoore]

Reproduced. Exact steps:

./build.py clean
./build.py
cd dist
bin/omero admin start
bin/omero admin ice server enable Web
bin/omero admin ice server start Web
# Checked logs, failed
bin/omero web settings
bin/omero admin ice server enable Web
bin/omero admin ice server start Web

then when I went to localhost:8000 I had the same error.
