kitten clipboard: Segfault

[sebastianlipponer]

Running echo This is a test | kitten clipboard works as expected. However, invoking the clipboard kitten in the wrong way, i.e. running kitten clipboard "This is a test" rather than the aforementioned command, results in a segfault:

kitten clipboard "This is a test"
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x899634]
