When trying to sync a large folder to cloud files, the task fails with an exception. The folder contains ~20000 items (700 MB or so). It worked fine the previous day, so perhaps something changed in the API response.

Also tried latest build 4.1.1 for Windows; tried syncing on Win2k3x86, Win7x64, Win2k8x64

Exception:
