Bug#1127561: tumbler: thumbnailing broken with gdk-pixbuf+glycin

[Jeremy Bícha]

Control: retitle -1 tumbler: thumbnailing broken with gdk-pixbuf+glycin
Control: forwarded -1 https://gitlab.xfce.org/xfce/tumbler/-/issues/107
Control: severity -1 grave
Control: affects -1 src:gdk-pixbuf
Control: block 1127158 by -1

OK, this does appear to have been triggered by today's upload of
gdk-pixbuf 2.44.5 which switched the loaders to use glycin.

This appears to be something that needs to be fixed in tumbler so I'm
reassigning.
