Summary

Tomáš Popela reported an accessibility blocker bug related to the 
gnome-initial-setup session, with Matthias Clasen noting a fix should 
be part of the final 49.0 update. Matthias Clasen discussed gdk-pixbuf 
transition issues affecting thumbnailers due to nested sandboxing, 
while Michael Catanzaro confirmed a thumbnailer blocker bug regarding 
missing thumbnails for video and music files. Michael Catanzaro also 
highlighted challenges with Rust packaging due to frequent new 
dependencies, and Chris Murphy raised concerns about image size 
increase, which Neal Gompa (Conan Kudo) attributed to additional 
firmware and a dracut change. Tomáš Popela and Neal Gompa (Conan

Details

Accessibility Blocker Bug

Tomáš Popela reported that Adrian provided a comment on an 
accessibility blocker bug related to greeter session settings storage. 
Matthias Clasen noted that a fix should be part of the final 49.0 
update, expected by the end of the week.

gdk-pixbuf Transition Issues

Matthias Clasen discussed a problem with nested sandboxing stemming 
from the Glycin gdk-pixbuf transition, which affects thumbnailers and 
build systems. Glycin is being updated to back off its own sandboxing 
efforts when running in an already sandboxed environment, which is 
expected to resolve issues with thumbnailers that use gdk-pixbuf.

Thumbnailer Blocker Bug

Michael Catanzaro confirmed a blocker bug regarding missing thumbnails 
for video and music files. To address this, Michael Catanzaro suggested 
reverting the previous removal of totem-video-thumbnailer, which 
depends on the Glycin fix. Neal Gompa (Conan Kudo) confirmed that 
totem-video-thumbnailer was removed from comps and would need to be put 
back.

Rust Packaging Challenges

Michael Catanzaro highlighted difficulties in updating Rust packages 
due to frequent new dependencies, explaining that Rust packages have 
been removed from general rotating packager duty. Neal Gompa (Conan 
Kudo) expressed concern about the increasing number of dependencies in 
Rust-based software and the lack of discipline in upstream maintenance, 
emphasizing the need for more shared expertise in Rust packaging to 
avoid packages becoming unmaintained or orphaned. Tomáš Popela 
suggested reviewing data from recent weeks to address this issue 
internally.

Image Size Increase

Chris Murphy raised concerns about the image size exceeding maximum 
limits. Neal Gompa (Conan Kudo) attributed the increase to additional 
firmware and a significant 40% increase in the init size due to a 
dracut change that was not tested earlier. Neal Gompa (Conan Kudo) 
stated that they would work on adjusting the dracut defaults to address 
the size increase.

Firefox Slowness Issue

Tomáš Popela and Neal Gompa (Conan Kudo) discussed a proposed blocker 
bug related to Firefox slowness, particularly on Android machines. 
Tomáš Popela noted that active debugging and work are ongoing to 
address the issue.

Suggested next steps

 * Michael Catanzaro will restore totem-video-thumbnailer.
 * Tomáš Popela will look at the data from the last few weeks to 
discuss internally what can be done within their resources and add the 
Rust packaging topic to the next meeting agenda.
 * Neal Gompa (Conan Kudo) will take care of the rough reviews and 
prepare an update of PackageKit to the very latest version.
