[Pkg-xfce-devel] Bug#763726: thunar: trouble with file associations since glib2.0 upgrade to 2.42

Package: thunar
Version: 1.6.3-1
Severity: normal

Opening files in Thunar (under XFCE) shows inconsistent behaviour with
respect to file associations. This happens since an upgrade of
libglib2.0-0 to version 2.42.0-1 from 2.40.0-5, and is apparently
related to the changes in GLib 2.41.x concerning the move of mimeapps
configuration to ~/.config/mimeapps.list (as documented in
/usr/share/doc/libglib2.0-0/changelog.gz, commit

More specifically, it seems like the [Default Applications] section is
shown and updated when file associations are set from Thunar, but the
first application in [Added Associations] is actually opened by Thunar
upon opening a file.

Manually opening ~/.config/mimeapps.list in a text editor and editing
the application order in the [Added Associations] section does the

Example: let an excerpt from ~/.config/mimeapps.list be

[Default Applications]

[Added Associations]

Thunar opens PDF files with evince. If the association is changed
within Thunar to xpdf, the file is modified to something along the
lines of:

[Default Applications]

[Added Associations]

but Thunar still opens PDF files with evince, because it is the first
application in the [Added Associations] section. However, the file
association shown within Thunar is xpdf.

On the same setup (and still running XFCE), Nautilus apparently works
fine, whereas PCManFM also shows odd behaviour. I interpret that
Thunar and PCManFM may both need some patching to work consistently
with the changes in glib2.0, but please let me know if this is a
glib2.0 bug, and feel free to reassign. Otherwise, I shall further
investigate the behaviour of PCManFM and file a bug against PCManFM as
well, as time allows.

Best regards,
