Do I really need to recompile ORBit2?
As I have found Valgrind far more useful in debugging than GDB, I looked for a way to reconcile them. The first thing I thought of was that a huge suppression file could resolve the readability issue. Google led me to http://live.gnome.org/Valgrind, which advises recompiling ORBit2 with the --enable-purify option (and only has an Edgy Eft suppression file which seems ineffective).
I'm just wondering if all GTK objects require this library; if not, do I really need to recompile? I'm not just asking because it's an inconvenience; I'd rather not work with the lower levels of my system until I can reinstall Ubuntu, because that kind of activity seems to trigger more system decay.
