i'm still seeing a segfault when using gtkmozembed - i'm not sure if it's the same bug - the backtrace looks different. 
let me know if it looks sufficiently different to warrant a new bug.
let me know if you want further data from gdb/valgrind or whatever.

setting LD_LIBRARY_PATH or MOZILLA_FIVE_HOME has no effect. 
neither does the adding the line "gtkmozembed.set_comp_path('/usr/lib/xulrunner-1.9.2.13')" to my script
i tried removing /usr/lib/xulrunner-1.9.2.13/components/compreg.dat but that had no effect
according to strace the library is not trying to access the compreg.dat stored in my firefox profile

my test script:

#!/usr/bin/python2.6
import gtkmozembed
data = """<html><head><meta http-equiv="content-type" content="text/html; charset=UTF-8" /></head><body></body></html>"""
html_doc = gtkmozembed.MozEmbed()
html_doc.render_data(data, long(len(data)), 'file:///', 'text/html')

backtrace:
