That means something happened in the UI that caused an uncaught exception. The 
application then sends the exception to the backend. If you have debuginfo 
packages installed it will de-obfuscate the exception into something human 
readable. These packages are not installed by default as the debuginfo is 
fairly large (~50M).

Run this command on the ENGINE to install the debuginfo packages.

yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-
debuginfo

Once you have done that and the UI.log has some more interesting info please 
open a bugzilla with the stack trace so we can fix the problem.

Thanks,
Alexander
