My apologies on the wild goose chase but after using valgrind on my fcgi process it is python cx_Oracle (would have never guessed that!) which triggers the segmentation fault when ldap.initialize() is called. Why it does this is beyond me but a simple alteration of my code makes the problem go away completely. I was creating a global oracle db cursor which I'm now creating inside the functions that use it.
I'm not sure about the glib c error and patch now. Using the original release without modification works so I will leave it at that.
