the tail of the strace follows the end of this email.

from what i can tell, pango opens up its rc files and gets glib to start
loading gconv modules. it seems that that is for converting between
character standards.

then it stops after glib opens the ISO8859-1.so module. i tried the
helloworld gtk example and it stops after loading ISO8859-2.so.

i don't know what the trouble is at all.

don't have ltrace and gdb is malfunctioning.

oh, well. thanks for the help!
