Description Brian Morrison 2026-03-26 14:08:39 UTC

Various icons and themes in claws-mail break due to the interaction between glycin, gdk-pixbuf2 and the recently obsoleted gdk-pixbuf2-modules-extra package.

This has been a constant feature of the glycin/gdk-pixbuf2 saga, and it's very difficult to understand why it happens as in claws-mail some themes are mostly fine (but not perfect) while others are badly broken.

Reproducible: Always



Expected Results:
Old icon formats should just work, even if the coders really hate them they are not going away.

glycin does not Obsolete the -extra package, they are obsoleted in gdk-pixbuf2 itself:

Comment 2 Brian Morrison 2026-03-26 14:18:15 UTC

OK, my apologies, I find this whole thing difficult to follow and understand. From what I read the removal of the modules-extra part of gdk-pixbuf2 meant that glycin was responsible for loading these icon formats. Not a programmer here.

Comment 3 Fabio Valentini 2026-03-26 14:25:31 UTC

Yes, glycin 2.1.0 is supposed to handle XPM / XBM images (at least to some degree). I agree that this whole thing is not easy to follow, I'm also mostly not involved in any of the decisions here, and just maintain the glycin package. :)

The mechanism that removes the -extra packages from systems on upgrade is the "Obsoletes" I linked above.
In a broader sense, yes, the XPM & XBM image support in glycin "obsoletes" the old plugin from gdk-pixbuf, but that's outside of the control of the "glycin" package itself, it's controlled by the configuration flags that are passed when the gdk-pixbuf2 package is built.

Comment 4 Milan Crha 2026-04-22 09:35:12 UTC

This change had been reverted in f44, shipping gdk-pixbuf 2.44.4 there and no newer.
