synapse chrashes when started

[Nalim Bictu]

When Sypnase is started, it crashes imediatelly, this is the output from the terminal.

I'm running Ubuntu MATE 15.10, it was running fine until now.

$ synapse

Try to start it with
GTK_IM_MODULE='' synapse

[Renaud Levesque (releve1403)]

Since a recent Lubuntu 15.10 update, I had the same bug (crash when trying to type after Synapse activated). It looks related to bug #1514104, as the change :
Exec=bash -c 'GTK_IM_MODULE="" synapse'
in /usr/share/applications/synapse.desktop solve my problem.
Simply calling "GTK_IM_MODULE='' synapse" was working only from the terminal.

Oh, I'm sorry, I didn't see the comments before.

I looked at the bug you linked, and adding

GTK_IM_MODULE='' synapse

to usr/share/applications/synapse.desktop solved it! I didn't need to add the bash part.

Thanks a lot!

Actually, I didn't add it, but replaced

Exec=synapse

with

Exec=GTK_IM_MODULE='' synapse

in /usr/share/applications/synapse.desktop

[Nalim Bictu (i2061845)]

After a few days it started crashing again.

I replaced

Exec=synapse

with

Exec=bash -c 'GTK_IM_MODULE="" synapse'

and it works now.

Note: if want synapse to open at login you have to add

bash -c 'GTK_IM_MODULE="" synapse'

as a command in Startup Applications.

I have the same problem on my Debian jessie with XFCE 4.10. Compiled synapse from source.

@pauk960: What do you mean with compiled from source? Did you use the latest bzr trunk or git master of synapse?

This commit should fix this bug as well:
