I have repeatedly encountered a problem with several programs that use open/save file dialogues.

Upon initiating these by trying to open or to save a file, the program freezes for about 10 seconds and then crashes. With libreoffice for example, I get the following error message when started from terminal:

Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.UDisks2VolumeMonitor: Timeout was reached (g-io-error-quark, 24)

(soffice:1466): GLib-GIO-ERROR **: 19:11:38.289: Settings schema 'org.gtk.Settings.FileChooser' does not contain a key named 'show-type-column'

Fatal exception: Signal 5

A stack trace follows.

I have read about a similar problem on AskUbuntu.SE, but the solution (multiple versions of /usr/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml) does not apply to me.

The file seems to have the appropriate contents (to me). Excerpt about the key mentioned in the error:

<key name='show-type-column' type='b'>
  <summary>Show file types</summary>
Controls whether the file chooser shows a column with file types.

How do I fix this problem?

  • As a workaround, it is possible to change the desktop theme to avoid the problem. (Should I post this as an answer?) Nov 1, 2019 at 16:35

I experienced this bug in 1.01 AppImage of Inkscape.

Mike Nealy gives an explanation and workaround in a bug report here

I've copied his workaround below:

Simply updating the schema to contain show-type-column isn't enough.

Downloading the newer schema file from https://gitlab.gnome.org/GNOME/gtk/-/blob/c925221aa804aec344bdfec148a17d23299b6c59/gtk/org.gtk.Settings.FileChooser.gschema.xml and installing it in /usr/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml, running "glib-compile-schemas ." in that directory and using Alt-F2 r to restart gnome-shell seems to resolve the issue with Inkscape 1.0.1.


For Inkscape 1.1 from snap you have to sudo snap remove inkscape && sudo snap install inkscape https://gitlab.com/inkscape/inkscape/-/issues/2495


I suspect the xfce4-theme I was using is faulty as of now, so I switched to another one as a workaround. This solves my problem.
