Now we know it's about failing fetch operation (in firebird source ../src/remote/interface.cpp:1899) in context of add_field_threadedcomment_rating_count migration step. Could you please check what the migration app does in this step? What calls and data are sent to fdb ? I would be difficult for me to reproduce, as I don't use Ubuntu/Debian, neither django & mezzanine. Pavel Cisar IBPhoenix

To nail it down I would need to know what command/call to FDB raises that, and what parameters were passed. At least, Python stack trace is necessary, as segfault in firebird client library is helpful as output from dev/null. regards Pavel Cisar IBPhoenix
