Application crashing(GLib-GObject-CRITICAL gtype.c:2458: inintialization assertion failed, use IA__g_type_init())

I wrote one so using qt , which works as a NPAPI plugin. This plugin will get loaded by firefox/QtWebKit based application.
My plugin is working fine with firefox , but when i tried to load same thing using qt webkit based application it is crashing by putting error as

*GLib-GObject-CRITICAL gtype.c:2458: inintialization assertion failed, use IA__g_type_init() prior to this function.
*

Please advise where I am going wrong.
