Package: gimp
Version: 2.10.6-3
Severity: normal

Dear Maintainer,

I was using gimp with an image when saw the warnings on the console -

~/Pictures$ gimp riot-web-settings-screenshot.png
Missing fast-path babl conversion detected, Implementing missing babl fast paths
accelerates GEGL, GIMP and other software using babl, warnings are printed on
first occurance of formats used where a conversion has to be synthesized
programmatically by babl based on format description

*WARNING* missing babl fast path(s): "R'G'B' double" to "CIE Lab double"
*WARNING* missing babl fast path(s): "cairo-ARGB32" to "R'G'B'A u8"

I did see it's a common warning and some have also experienced crashes due to it
as well.

https://forum.manjaro.org/t/missing-fast-path-babl-conversion-detected/50518

While am not experiencing crashes atm, the warnings are disconcerting
at the very least.

FWIW, I did as shared on the manjaro thread without any discernable result -

~/.config$ mv GIMP/ GIMP_old/

$ gimp
Missing fast-path babl conversion detected, Implementing missing babl fast paths
accelerates GEGL, GIMP and other software using babl, warnings are printed on
