Problem with one note (The server threw an exception)

[rmueck]

I am having a problem with one specific note. I created a Markdown note with out specific title. It is shown in the list of notes with date/time as title. When i try to open it i get this error message:

ERROR: The server threw an exception. Details:

(remote):0: failed: remote exception: remote exception: remote exception: expected headersComplete; HTTP response from sandboxed app had incomplete headers.
stack: 0x671600 0x5065f0 0x506fb0 0x549a40 0x543670 0x506fb0 0x712530 0x709d00 0x6ceea0 0x6d1a20

All other notes are opening fine. Any help is appreciated!
