Public bug reported:

Certain applications have associated input hangs, where no key input
events can be sent which sometimes clear after some time, and in at
least one case (Inkscape), this is eliminated by running from Start->Run
as follows, hence overriding the declaration of GTK_IM_MODULE in
/etc/X11/Xsession.d/70im-config_launch , distributed in im-config...

bash -c "unset GTK_IM_MODULE && inkscape"

A permanent fix on my machine could be to modify the 70im-config_launch
file, or declare an overriding export in some later .rc file. Anyone
know where I should make this declaration if not modifying package-
maintained files?

An alternative solution could be to install scim-gtk-immodule and run...

bash -c "export GTK_IM_MODULE=scim && inkscape"

Similar behaviours are experienced with Kupfer - minutes of hang with
apparently no input events being passed, followed by (sometimes)
unfreezing.

I'm running Lubuntu Utopic with LXDE and Compiz (minimal dependencies on
GTK), so it's feasible that some component is not properly declared in a
dependent package.  I can't find whether there is in fact a xim module
available and running anywhere on my system. How can I check?

Other input issues relating to out-of-order key event delivery to
Chrome-based applications are experienced on the same build, but I think
this may be an independent bug, ostensibly resolved by declaring
IBUS_SYNC_MODE=1
https://code.google.com/p/chromium/issues/detail?id=456766 but thought I
should mention as it's kind of in the same subsystem and may be linked.

I speculate that there is some missing dependency or bad configuration
in the default presentation of IM capabilities, which eventually causes
a DBUS timeout or similar, eventually causing a fallback without any
international input, but which is functional.
