I have been using synapse with cairo-dock for quite some time now without a hitch. Works very well and I need it on my machine. But after a reinstall of Ubuntu 14.10 it has started crashing as soon as any keyboard input is sent to it.

The messages when synapse is run from the terminal are given below. Synapse version is 0.2.99.1 from the synapse core repo.

(Note: " Binding <Super>y failed because the key combo is being used by Gnome-do at the moment :). )

WHAT WORKED FOR ME: Mario's suggestion that I set GTK_IM_MODULE=' ' before running synapse.

WHAT DID NOT WORK: the im-config and sudo im-config stuff

Cheers
