I now realized why I'm confused: because I found I had installed 1.9.1 
on some machine and I've installed ruby-debug19 there along with 
ruby-debug-base19. This is 1.9.1p387 with ruby-debug-base19 (0.11.23) 
and ruby-debug19 (0.11.6) .

Now I see the current version of ruby-debug-base19 is now at 0.11.24, 
and that's actually the package which doesn't work anymore.

Is this a bug I should report? For some strange reason on the ruby-debug 
page on githib there's no "Issue" tab ...

Thanks for the useful link,
