Crashes on keyboard input

[Lee Hyde]

For approximately a week now, whenever I type anything into Synapses input/search box Synapse crashes. Synapse starts fine (as far as I can see), is summoned and visible on-screen, but typing elicits no visible input in Synapse and it swiftly crashes there after. Running Synapse via terminal results in the following output (note that the last line corresponds to when I started typing input):

I had the same issue and it was caused by the xim input method. For some reason (probably my own) synapse suddenly switched from ibus to xim, and the problem started.

Try:
1. Remove ~/.xinputrc
2. Run im-config and set it to Auto
3. Restart X

Then, run synape again and verify that the debug printout says:
[20:36:09.063634 Info] [GuiViewEssential] Using ibus input method.

If is still shows xim, run sudo im-config

All the best,
Niklas

[Joe Gibken (joegibken)]

Edit: Oops. Jejeh. Kindly disregard #3 & #4. Sorry.

I'm also getting the same error. And I can't seem to change xim into ibus and I don't have ~/.xinputrc. Even when I used sudo im-input, the "xim input method" is still there. (Of course, I already restarted X).

This is what shows in my im-config now:

Current configuration for the input method:
 * Active configuration: ibus (normally missing)
 * Automatic configuration: ibus (normally ibus or fcitx or uim)
 * Number of valid choices: 2 (normally 1)

My version is synapse 0.2.99~bzr520+i18n+522~ubuntu14.04.1

Any help in fixing this is appreciated.

Try to set GTK_IM_MODULE='' before running synapse

$ GTK_IM_MODULE='' synapse

[pramathesh ambasta (pramathesh-ambasta)]

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

Using "GTK_IM_MODULE='' synapse" in a terminal also worked for met I didn't want to have to runsynapse in a terminal every time I used it I added these lines to my .bashrc file located in the HOME folder.

# set gtk im module to default (to make synapse work)
 export GTK_IM_MODULE=" "

The first line is just for clarity's sake and not necessary, but now Synapse works properly.

[jay armstrong (jayarmstrong)]

+1 in Xubuntu 15.04

workaround in #6 works

[James Pack (james-packjr)]

#6 'Try to set GTK_IM_MODULE='' before running synapse

$ GTK_IM_MODULE='' synapse'

Works for me too on Ubuntu MATE 16.04

[Song (syqlds)]

#6 works but still waiting for the fix release

[Guy Verrijdt (gverrijdt)]

#6 works for me too, but can't seem to make it work on autostart, so waiting for the fix as well...
