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 Stack:
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'> <default>true</default> <summary>Show file types</summary> <description> Controls whether the file chooser shows a column with file types. </description> </key>
How do I fix this problem?
