@Zsombor and Victor, This bug was indeed caused by the same regression in bug #1401883. On installing the latest SDK toolkit staging 1424 rev on Nexus 4, I am able to enable/disable alarms successfully. Thnx Zsombor for the fix. As such I am marking this bug fix committed.
On a side note, I have also noticed that the clock app now crashes often when pressing on the "Add new alarm" button. But I will investigate more on that and create a new bug to track that issue.
