Did a dup today (last was Sep 15), and claws-mail lost all of its icons. claws-mail wasn’t updated so this problem is caused by one of the theme/icon/pixbuf/gtk updates removing something or changing a path.
There are no icons on buttons, the Help->Icon Legend is blank, there’s not a single icon shown anywhere.
The claws-mail config has the oh so helpful path setting:
pixmap_theme_path=INTERNAL_DEFAULT
I don’t know where to look for what changed let alone how to fix it.
I tried rebuilding claws-mail but that didn’t fix anything. So I downloaded and installed these older .rpm that the update changed and claws-mail works again:
None of the links or bug reports show the true cause of this issue: gdk-pixbuf no longer enables xpm (and other older formats) support by default. It is up to the distro to enable it or provide a gdk-pixbuf-loader for that format. https://www.claws-mail.org/bugzilla/show_bug.cgi?id=4877
