Crash on quit after adding wrong links in $XDG_DATA_HOME/color/icc

[su_v]

follow-up to Bug #494932 “[osx] search path for color profiles doesn't include '/System/Library/ColorSync/Profiles'”

adding (carelessly ;) symbolic links to the missing profiles in '/System/Library/ColorSync' in '~/.local/share/color/icc' with:

LeWitt:icc suv$ ln -s /System/Library/ColorSync/* .
LeWitt:icc suv$ ll

Inkscape fails to load any pixmap images:
**: Pixbuf theme: Cannot load pixmap file /Volumes/blue/src/Inkscape/Inkscape-0.47-1.LEOPARD+/Inkscape-047-1.app/Contents/Resources/themes/Clearlooks-Quicksilver-OSX/gtk-2.0/Scrollbars/trough-scrollbar-vert.png: Failed to open file '/Volumes/blue/src/Inkscape/Inkscape-0.47-1.LEOPARD+/Inkscape-047-1.app/Contents/Resources/themes/Clearlooks-Quicksilver-OSX/gtk-2.0/Scrollbars/trough-scrollbar-vert.png': Too many open files
(tons of related error messages snipped)

as well as this pango error:
Pango-ERROR **: Unable to open font file /Users/suv/Library/Fonts/Vera.ttf for font Bitstream Vera Sans 512, exiting

and crashes on exit (Crash report attached).

reproducible with Inkscape 0.47-1 and Inkscape r8878 on OS X 10.5.8

crash report with Inkscape 0.47-1 from sf.net

similar result with local build (bundled as app) from bzr (r8878) using the tango/hicolor gtk-icon-theme (from KK) and a custom gtk-theme (default and 'mist' engine).

Contents of the link that lets Inkscape crash:

LeWitt:~ suv$ du -sch /System/Library/ColorSync/Calibrators/

LeWitt:~ suv$

removing '~/.local/share/color/icc/Calibrators' restores normal behavior of Inkscape.

Appears to have been partially due to not closing directories, and in two different sections of code doing similar-yet-slightly-different directory walking.
