After a system update my owncloud sync client will not open its configuration window. Logs give the following: Gtk-Message: Failed to load module "pantheon-filechooser-module" Any suggestions? Edit: Not sure it matters but here is some more info. $ uname -a Linux elemos 3.16.0-46-generic #62~14.04.1-Ubuntu SMP Tue Aug 11 16:27:16 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Owncloud was installed through the software center. I have tried reinstalling the client via software center with no improvement. Googling give conflicting information that pantheon-filechooser-module is "not in vanilla elementary os yet" or "is in but not enabled." I tried enabling with the following command and a restart. No improvement: gsettings set org.gnome.settings-daemon.plugins.xsettings enabled-gtk-modules "['pantheon-filechooser-module']"
Figured it out some more. Editing ~/.local/share/data/ownCloud/owncloud.cfg and set "monoIcons=true" to "monoIcons=false" allowed me to open any owncloud window once. After that it reverts to previous broken behavior.
