New issue 1454 by [email protected]: Assertion in gtk+ IM module
http://code.google.com/p/ibus/issues/detail?id=1454
Currently gtk+ doesn't immediately switch the IM module when the XSETTING
gtk-im-module changes. To fix that I'm proposing the attached patch to be
pushed into gtk+ upstream.
This patch introduces a problem with the default configuration of the IBus
gtk+ IM module. An assertion is hit out of the _key_snooper_cb() function.
In general it's not a good idea to use gtk+ key snoopers and the IBus
module seems to otherwise work all right if I set the env var
IBUS_DISABLE_SNOOPER. IMO you should just stop using the key snooper but
that's not up to me to decide so I'm reporting here so that you can decide
on the better fix.
Here's the assertion:
