Comment 6 for bug 933058

The build log for most recent Oneiric 64bit build of trunk (inkscape.dev PPA) indicates to me that the problem is not really a glib bug, but an issue with the GDL sources in Inkscape:

Our automated build log filter detected the problem(s) above that will
likely cause your package to segfault on architectures where the size of
a pointer is greater than the size of an integer, such as ia64 and amd64.

This is often due to a missing function prototype definition.

Since use of implicitly converted pointers is always fatal to the application
on ia64, they are errors. Please correct them for your next upload.
