Public bug reported:
It was working fine. Crashed now after apt do-release-upgrade.
$ lsb_release -rd
Description: Ubuntu 26.04 LTS
Release: 26.04
$ apt-cache policy thunar
thunar:
Installed: 4.20.7-1
Candidate: 4.20.7-1
Version table:
*** 4.20.7-1 500
500 http://archive.ubuntu.com/ubuntu resolute/universe amd64 Packages
100 /var/lib/dpkg/status
I expect it to show and hide dot-files as with the previous version.
Instead, it crashes. Tried the following, it always crashed when hiding
files (when hidden files are not visible, CTRL + H shows them, undoing
it crashes 100%):
- rm ~/.config/Thunar/accels.scm && thunar
- GTK_CSD=0 thunar
- GSK_RENDERER=cairo thunar
- LIBGL_ALWAYS_SOFTWARE=1 thunar
- thunar -q && thunar
- THUNARX_DISABLE=1 thunar
- rm -f ~/.config/gtk-3.0/accels && rm -f ~/.config/Thunar/accels.scm && rm -f
~/.gtkrc-2.0 && thunar - q && thunar
- pkill gvfsd-metadata && rm -rf ~/.local/share/gvfs-metadata && thunar
- mkdir -p /tmp/xfce-clean/{config,cache,data} &&
XDG_CONFIG_HOME=/tmp/xfce-clean/config XDG_CACHE_HOME=/tmp/xfce-clean/cache
XDG_DATA_HOME=/tmp/xfce-clean/data thunar
The only thing that works is hiding the files via xconf-query: xfconf-
query -c thunar -p /last-show-hidden -s false
A little more info, in case this helps,
$ ldd $(which thunar) | grep gtk
libgtk-3.so.0 => /usr/lib/x86_64-linux-gnu/libgtk-3.so.0
