$ echo test > x.txt
$ cat x.txt
test
$ cat x.txt | xclip -in -selection clipboard
$ xclip -out -selection clipboard -t image/png
test
$ xclip -out -selection clipboard -t image/png
[1]    619206 segmentation fault (core dumped)  xclip -out -selection clipboard -t image/png

Version 0.13:

$ echo test > x.txt
$ cat x.txt
test
$ cat x.txt | xclip -in -selection clipboard
$ xclip -out -selection clipboard -t image/png
test
$ xclip -out -selection clipboard -t image/png
test

Explaination:

The -t option does not work with -in when specifying inputs.
An input by default as text but can be read as image/png TARGET.

Expect:

$ echo test > x.txt
$ cat x.txt
test
$ cat x.txt | xclip -in -selection clipboard
$ xclip -out -selection clipboard -t image/png
Error: target image/png not available
$ xclip -out -selection clipboard -t image/png
Error: target image/png not available
