If e17 is compiled with tslib but during runtime the environment variable
TSLIB_TSDEVICE is not set, ecore will accidentally use the file descriptor 0
(probably stdin) for tslib.
The problem is that _ecore_fb_ts_fd is initialized to 0, which is BAD BAD BAD
for file descriptors. It should be initialized to -1. The attached patch fixes
this.
