I your transaction an error happens, but -stack-list-locals nevertheless 
returns the locals, and I wouldn't have a real problem in my debugging session.

I my case, -stack-list-locals does not return the locals at a all. Comparing 
your output and my output, the difference is the source of error. In your case 
an exception is thrown in the to_string method of the pretty printer. This 
seems to be handled properly. In my case the pretty printer methods don't 
throw. The error occurs later when gdb accesses one of the elements returned 
as children by the pretty printer.
