It has something to do with the way GTK handles the arguments
to XSetICValues. There are two possibilities:

- The code was making some impropoper assumptions about 
  how va_args is implemented. This has been fixed since 0.99.7,
  so hopefully 0.99.8 will fix your problem.

- The code is using some (as far as I can see) undocumented
  features of XSetICValues. If this is the problem, it will
  take a some more substantial to fix up. Hopefully, that
  isn't the case.

When using X11R5, you may be best off using the --disable-xim
configuration option when configuring GTK, which will eliminate
the relevant portions of the code.

There was some debate over the issue earlier, and the majority
consensus was to add it (it is done automatically by the list
software). The proponents were people who don't automatically
have their incoming mail sorted.

(I use Gnus, and that has a nice feature where it can be 
 set up to remove such tags so I never see them any more)
