The default for Gentoo is to install applications without debugging 
symbols. The next step in trying to diagnose this issue is to rebuild 
with debugging enabled and try again. Hopefully that will provide some 
more meaningful information. See http://www.gentoo.org/proj/en/qa/
backtraces.xml for all the details on how to do this.

Another approach may be to run the application with strace to see what 
kind of system calls it is making just before crashing. Sometimes this 
provides a clue, e.g. an app crashing right after being unable to open a 
particular file may have bad error handling and assumes the file must be 
there.

Kind regards,

Hans
