I haven't compiled a debug version of gideon. What I get from this operations is 
always the following: 
 
Program received signal SIGINT, Interrupt.

Another problem which I found was the lockup on exit. I don't know if I am right in 
reporting this here of if it is better to open another bug. However gideon blocks until 
killed on exit (if a project is open). this is the backtrace I obtain from GDB 
 
 Program received signal SIGINT, Interrupt.
