Hi Matt.
For some reason, your system generates an 'ENTER' key (keycode 36) event after the application has closed. So the application has run correctly, but during clean-up it gets a spurious key it cannot handle.
Can you try with another app and see if the same happens?
Alternatively, try df_input from DFB-examples.

Hello,

I am trying to run dfbinfo on directfb-1.2.8 running under X11 on Ubuntu x64.  
Everytime I run it, I get a black window and a Caught signal 11 (at 
0x7f956d52c008, invalid address) error.  I also noticed that it is not using 
XShm (not sure if thats important).

The only thing I did differently is changed the 'prefix' when I ran configure.

Thanks for your help.

Here is the error log
