In bug 99252 I found out that gnomebaker-0.4 fails on the file /usr/share/icons/Rodent/scalable/mimetypes/gnome-mime-text-x-patch.svg which is part of xfce-extra/xfce4-icon-theme. The error is gnomebaker: art_render_gradient.c:338: art_render_gradient_linear_render_8: Assertion `offset_fraction <= stops[ix].offset' failed. After removing the file, gnomebaker starts as assumed. Run xmllint -valid -noout <file.svg> on these svg-files and you will find out that they don't confirm to the svg-DTD. Probably that's causing the error.
I'll pass along upstream and see what I can find out
Very old bug... But still valid. This svg has not been fixed in xfce-extra/xfce4-icon-theme-4.2.3.

#svg, Freenode - [18:52] < darobin> if gnomebaker fails on SVG that is not valid then gnomebaker is at fault [18:52] < darobin> there is no requirement on SVG to be valid to display correctly [18:53] < darobin> it should just ignore the invalid element and its descendants
Xfce upstream bug http://bugzilla.xfce.org/show_bug.cgi?id=2724 (RESOLVED, INVALID)
