iOS & iCloud: Broken iCloud data causes kbd process to crash constantly and drains battery

On Stackoverflow I was told to come here. Since a few days ago my iPhone 5s is getting unusually warm and the battery drains REALLY quick, like in 4-5 hours. I tried turning all the usual suspecty off (location service, cellular data, push, etc.) but no change. Now, when looking through the crash logs on the device, I found a huge number of crash reports for the kbd process. There is a crash log every ~30-60 minutes and they all contain something like this:

{"app_name":"kbd","bug_type":"185","name":"kbd","os_version":"iPhone OS 7.1.2 (11D257)","version":"???"}
