Ah, this is a bug in Inkscape::LayerManager::_rebuild(). Everything after the call to _clear() should be skipped if _document is NULL.
Feel free commit a fix along those lines, I may not get to it soon.
Done.
Thanks a lot. Unfortunately this got rid of the first messages[1] but Inkscape still crashes with the message: $ ./inkscape
Emergency save activated! Emergency save completed. Inkscape will close now. If you can reproduce this crash, please file a bug at www.inkscape.org with a detailed description of the steps leading to the crash, so we can fix it.

Gdb log with a break points where I thought they could be useful:

Breakpoint 1, 0x93360cc4 in _handleWindowNeedsDisplay ()
At this point the main window has appeared but is empty (just
grey without even icons)

At this point icons appeared. However this point cannot always
be reached. Most of the time, stepping from there reaches the EXC_BAD_ACCESS failure below directly.
(gdb) s Single stepping until exit from function __CFRunLoopDoObservers, which has no line number information.
Breakpoint 1, 0x93360cc4 in _handleWindowNeedsDisplay () (gdb) s Single stepping until exit from function _handleWindowNeedsDisplay, which has no line number information.
Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x0000003c 0x93360ce6 in _handleWindowNeedsDisplay ()
Is there something else I can do? _handleWindowNeedsDisplay is not Inkscape nor GTK specific, all OS X programs use this apparently (so it must be gtk-quartz related but not gtk in itself). However I guess there must be a way of tracking down what causes it to fail more properly.
Thanks in advance for your help.
