Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1105617
Description of problem:
We need to handle the case when required lock is already taken by a task.
UI should throw proper error message. Like I tried to install a package on remote machine via UI and somehow I double clicked the pakage install button.
And production.log thrown a long exception with 500 internal server error. Hpwever I didn't see any error on UI.

Later I tried to install another package when install for one package is already on-going. And this time too I found same error in production.log and no change on UI. Neither the package install button submitted nor any error raised on UI.

log snippet from production.log:
