After today's system update, a run of uim-xim will result in an error:

> uim-xim --trace-xim --trace

I am using uim-1.8.6-2 with anthy-9100h-3.
Unfortunately, I do not know how I get further debug information.
I have not touched my configuration files in any kind. With the same configuration, uim-xim is running on several other machines,
for example on Debian Stable with uim-xim-1:1.8.1-4, I get:
