Segmentation fault in g_main_context_prepare()

Hi,

I have a Gtk application. It runs when when I launch it at command
prompt in a shell.
But when I try to launch it from another C program, like this:

int main( int argc, const char* argv[] )
{
    char *args[2] = { "testarg", 0 };
    char *envp[1] = { 0 };
    execve("/home/michael/MyGtkApp",args,envp);
}

My program crashes with this.
Program received signal SIGSEGV, Segmentation fault.
0x007e5f4e in g_main_context_prepare () from /lib/libglib-2.0.so.0
(gdb) bt

Does anyone has any idea?
