capplets fail to run

[Victor Kostyuchenko <kvic molbio siobc ras ru>]

Dear GNOMErs!

I've encountered such a trouble:

gnomecc and e-conf do not run on my machine, as well as other capplets.
They do things like this:
-----
<molbio:/usr/people/kvic>gnomecc

** CRITICAL **: file giop-msg-buffer.c: line 710
(giop_recv_buffer_unuse): assertion `buffer != NULL' failed.

** CRITICAL **: file giop-msg-buffer.c: line 457

and do not do anything. What is wrong with them (or me:)?
My system is SGI with IRIX 6.5, C compiler is egcs.

Thanks,
Victor.
