I'm not sure though whether it's the app itself, or some of its libraries, etc. See attached output of "valgrind --undef-value-errors=no --leak-check=full --log-file=terminal.log Terminal".

I think this is the culprit. The below leak appears in 4 slight variations (13 MB each) at the end of the log, explaining the 50 MB total leak: ==25733== 13,471,920 bytes in 62,370 blocks are definitely lost in loss record 5,384 of 5,387 ==25733== at 0x4026EA8: malloc (vg_replace_malloc.c:236) ==25733== by 0x4BD463B: cairo_pattern_create_linear (in /usr/lib/libcairo.so.2.11000.2) ==25733== by 0x402DB51: gradient_draw_shaded (in /usr/lib/gtk-2.0/2.10.0/engines/libxfce.s o) ==25733== by 0x4033BE6: draw_box (in /usr/lib/gtk-2.0/2.10.0/engines/libxfce.so) ==25733== by 0x4364FBD: gtk_paint_box (in /usr/lib/libgtk-x11-2.0.so.0.2400.10) ==25733== by 0x431A4DB: draw_stepper (in /usr/lib/libgtk-x11-2.0.so.0.2400.10) ==25733== by 0x431A9ED: gtk_range_expose (in /usr/lib/libgtk-x11-2.0.so.0.2400.10) ==25733== by 0x42D2603: _gtk_marshal_BOOLEAN__BOXED (in /usr/lib/libgtk-x11-2.0.so.0.2400. 10) ==25733== by 0x47A0276: g_type_class_meta_marshal (in /usr/lib/libgobject-2.0.so.0.3000.3) ==25733== by 0x47A16D2: g_closure_invoke (in /usr/lib/libgobject-2.0.so.0.3000.3) ==25733== by 0x47B4EFB: signal_emit_unlocked_R (in /usr/lib/libgobject-2.0.so.0.3000.3) ==25733== by 0x47BD7E2: g_signal_emit_valist (in /usr/lib/libgobject-2.0.so.0.3000.3)
xfce-base/libxfce4util-4.8.2? Upgrade to Xfce 4.10 before doing any debugging with anything Xfce related. Which GTK+ theme/engine are you using? And after upgrading, report this to http://bugzilla.xfce.org/ and add the link to the "See also: " field.
And be sure to use also ~arch of gtk-engines-xfce wrt bug 408529. Basically, don't test this with stable but ~arch system.
