emerge info

This problem has caused me so much trouble, yet im not 100% sure its glibc...

I had the above problem for a while. I tried building a parrallel gentoo system on ~amd64, and behold, I still had the same problem!

I later found this thread https://bbs.archlinux.org/viewtopic.php?id=148063 which led me to my crusade of attempting to downgrade glib while still being on ~arch. unfortunately i found this too time-consuming, obfuscated and difficult, so I switched back to stable+keywords. Using glib-2.32 I dont have the above problem.

I may try keywording glib2.34.x when i calm down, but for now i'm happy for a functioning system

How to reproduce: use nautilus-2.32.x with glib-2.34.x. make sure nautilus is trying to load...say 10 thumbnails.

Same here. Sort it out by downgrading glib.

Will need to check if this mate-desktop fix can be adopted by our gnome-desktop-2.32:

Update .thumbnails reference in nautilus

I'm not sure if this code is actually touched. It was removed upstream.
https://git.gnome.org/browse/nautilus/commit/libnautilus-private/nautilus-thumbnails.c?id=f9c6ca979f753339b91c125c363a927fceb64283

But it doesn't hurt to fix it just in case.

I've tested both of those patches locally, and it seems to fix the thumbnailing issue (using glib-2.36.x).

Fixed in gnome-desktop-2.32.1-r2, sorry for the very long wait.

The nautilus patch should not be needed as far as I can tell.
