I share your frustration. A great example of this is f-spot, which
crashes with no error message at all.
Anyway, any program should give helpful error messages, so just
showing a popup with the stderr output would probably not help Joe
User but is better than nothing, I agree.
It is better to write a gui against a library instead of using a
console backend IMHO because you otherwise lose too much information.
You probably need to file bug reports against the specific offenders.
