If the summary and description of the package are correct, then only comment #1 matters

IMHO the above implies that it isn't supposed and tested to work in another DE.

Apart from that, the URL is wrong, it should be 
https://gitlab.gnome.org/GNOME/gnome-color-manager

Assigning to the GNOME maintainers, CC'ing papoteur.

Trying this on an up-to-date Cauldron system (which should reflect an updated installed ISO); I am finding that several of the desktops no longer start! Gnome both ways, Mate, at least. Where the desktop does start OK, gcm-viewer also starts OK: I think at least LXDE, Xfce, LxQt, Plasma.

installed all DE from i586 Mga9 beta CI.
on reboot changed DM from GDM to LightDM,
reboot and logged in to XFCE

updated to latest.

open a terminal and tried gcm-viewer:

[work@localhost ~]$ gcm-viewer 
[work@localhost ~]$ gcm-viewer

gcm-viewer with no core dump launch successfully.

and after a reboot for new kernel:

Hello,
This kind of problems is of type memory overwrites. The program writes some data at a place it shouldn't. This is why the error isn't systematic.
There is no new release since 2020. This error is not reported upstream. All that I can try is to rebuild it, to be sure it use the last libraries, what I will do.
I can't try to debug it.

Thanks Ben for your convincing tests on Xfce.
And Yves for an explanantion & offering to rebuild it.
Note Ben's report is 32-bit. My tests were 64-bit.
After papoteur's rebuild, can you Ben please re-try this for each desktop x32. One crash per desktop suffices. Tedious, yes; but less so than re-booting between them. I will re-run the x64 desktops.
Need to wait for these results before judging what to do; at worst, drop the pkg.

Baptiste (new tester) ran a x86_64 all DE net-install ~ 9th Mar, after the beta1 rnd5 arrived for testing.
he sent me a copy of his guiApps.txt, guiResults.txt and guiFails.txt.

gcm-viewer was not listed, so it does appear to be arch specific.

info;

when the application does launch successfully, attempting to select another profile type causes a:

malloc(): unsorted double linked list corrupted
Aborted (core dumped)

installed from Live-Mageia9-beta1-Xfce-i586

My assumption is that the error is specific to 32bits arch. Something like the computation of the space of a structure which is different in 32bits than in 64bits. And it is not reported upstream because the usage of 32bits arch is small.
To identify the problem, the tool valgrind is the way.
https://valgrind.org/docs/manual/quick-start.html

Created attachment 13701 [details]
valgrind output

I installed a 32bits VM and I reproduce the problem.
Thus I get a trace from valgrind.
Culprit seems to be in liblcms2
Should we report that upstream?

I found this:
https://github.com/hughsie/colord/pull/146
but we should already have
and this:
https://github.com/mm2/Little-CMS/issues/344
We should try to backport this:
https://github.com/mm2/Little-CMS/commit/a9e4601ceb3a185d4f78cc0cfbd285cf0c399e9d

I applied https://github.com/mm2/Little-CMS/commit/a9e4601ceb3a185d4f78cc0cfbd285cf0c399e9d
After updating to liblcms2_2-2.14-4.mga9.i586.rpm I get gcm-viewer running fine.
I close this report. Reopen if this is not the case for you.

Resolution: (none) => FIXED
Status: NEW => RESOLVED

Great work Yves.

Forgot to try it...
 $ rpm -q lib64lcms2_2
lib64lcms2_2-2.14-4.mga9
Just on Xfce, it starts fine as previously, and Ben's test comment 9 gave no trouble: all profiles could be selected.

Mageia-9-beta1-i586.iso
DATE.txt: Mon Feb 13 12:37:07 PM CET 2023

single DE Xfce install.

at initial desktop presentation:
  
[work@localhost ~]$ gcm-viewer 
malloc(): unaligned tcache chunk detected
Aborted (core dumped)


update to system includes:

liblcms2_2-2.14-4.mga9.i586 

after updates applied:

[work@localhost ~]$ gcm-viewer 
[work@localhost ~]$ 

manually closed application.

selecting all profile types and tabs no longer crashes application.

yet to check Gnome but looks good.

Thanks
