Thank you for taking the time to do this. Obviously I'm happy with the code itself. I expect the questions here may be (a) whether these changes are too large to be added to 4.7 and (b) whether the new i18n strings are okay (see below). I'll defer to the opinion of others there...


debuggers/gdb/debugsession.cpp
<https://git.reviewboard.kde.org/r/121527/#comment50259>

    There is a new string here.
    
    Since it fixes the issue of not getting proper feedback when something fails that should be okay, but I guess it still needs to be ACK'ed by some people?



debuggers/gdb/gdbframestackmodel.cpp
<https://git.reviewboard.kde.org/r/121527/#comment50260>

    This might also be a string that doesn't yet appear anywhere.



debuggers/gdb/gdblaunchconfig.cpp
<https://git.reviewboard.kde.org/r/121527/#comment50261>

    Yet another i18n addition.
