Bug 296841: graphics/gimp3-app: lua errors when running in scripts without =
GUI
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D296841



--- Description ---
When running GIMP in scripts without GUI, it prints a LUA error on startup:

/usr/local/bin/lua51: /usr/local/share/lua/5.1/lgi/namespace.lua:189:
gtk_init_check() failed
stack traceback:
	[C]: in function 'error'
	/usr/local/share/lua/5.1/lgi/namespace.lua:189: in function 'require'
	/usr/local/share/lua/5.1/lgi/namespace.lua:170: in function
</usr/local/share/lua/5.1/lgi/namespace.lua:155>
	(tail call): ?
	....gimp.extension.goat-exercises/goat-exercise-lua.lua:29: in main
chunk
	[C]: ?

The error is FreeBSD-specific, i.e. with the same test script, it runs with=
out
this error on different Linux distributions, NetBSD, OpenBSD, Solaris
(OpenIndiana), and MacOS. The error can be ignored (the output is generated
regardless of the error message), but it may be useful to take a look into =
the
root cause. May be GIMP tries to load broken LUA scripts.

Attached is a simple script to trigger the error. It downloads GIMP-Scripts
(https://www.nntb.no/~dreibh/system-tools/#gimp-scripts) from the System-To=
ols
collection (https://www.nntb.no/~dreibh/system-tools), as well as a test im=
age,
and then runs the mosaic effect script (source:

ic).
