Fixed:
a) problems with keyboard: It's not really a bug. Mac OS X, for reason that evidently were valid when NeXT Step OS was designed, dispatches event to menus at a higher priority than keyboard event processor. So the menu with accelerators "sucks up" the event before it even reaches the GDK (or any other event processor) delegation system. If there are accelerators that overlap with key events , without modifers, they won't be prcessed as regular keyboard events, but as menu accelerator (the 'g' that triggers "Toolgradient" being a good example) . The fix is to modify mac.xml such that all those accelerators that overlap with simple key events are removed. I've done so. I've fixed all cases I was able to find. Let me know if you run into more.
b) clipboard exchange with GIMP. The problem is really with GIMP, not Inkscape. Given that GIMP uses the unpatched gtk2+quartz library, it can only import TIFF images from the clipboard. TIFF is not mentioned in the Inkscape Info.plist, thus Inkscape does not export TIFF format to the clipboard. I've modified Info.plist , so now Inkscape and GIMP can talk via TIFF - Inkscape now exports TIFF (among a host of other formats, to the clipboard).
