Gnome shell segfaults with librsvg-2.54.4 on musl.

Can't get gdm or gnome desktop, after boot "I get a Oh no! Something has gone wrong.", if I try to start the gnome-shell manually I get the same error message but this time with a "log out" button. Guessing this is called the fail whale screen.

I'm using musl gcc with librsvg 2.54.4 on gentoo. Tried debugging and found the segfault occurs when reading a SVG. I've tried to point out which svg is causing the issue, unfortunately couldn't do so.

I've tried reading the svg using gdb with the following method

• Fire up gbd
• run gnome-shell with some args
• let it crash
• get back trace, and select the load_sliced_image frame.
• p g_file_get_uri(data->gfile)

This is how I was trying to find out which SVG causes the problem. However when I try p g_file_get_uri(data->gfile) I get Thread 7 "pool-gnome-shel" received signal SIGSEGV, Segmentation fault. g_file_get_uri (file=0x7fffe6a0d8c0) at ../glib-2.72.2/gio/gfile.c:655. You can see that in log.

My gdb log showing what I did

PS Its works with librsvg version 2.40.21
