Sounds very much like the issue that was recently fixed in 4.0.6

Hi,
since a few days, after the upgrade my dev machine to the nightly repo
of 4.0.7, I'm getting these kind of errors from the WebUI after a few
minutes the ovirt-engine is up:

Error while executing action: A Request to the Server failed:
java.lang.reflect.InvocationTargetException

The errors go away if I restart the engine service, but after about 15
minutes they show up again. These errors are very annoying as I cannot
use the UI unless I restart the engine.
When I use my Mac I also get other errors like this:

ERROR: Possible problem with your *.gwt.xml module file. The compile
time user.agent (gecko1_8) does not match the runtime user.agent value
(safari). Expect more errors.

Does anyone knows if those errors will be corrected in a future release?
Thanks,
