Crashing on executeQuery:parameters

[mpogra]

Hello,

First of all thanks for creating such wonderful small framework wrapper for Sqlite for thread safety. I am trying to integrate it in my app that uses 3 threads to read/write content in database, It is working at first sight very well except I am getting crash regularly when trying to select rows from database. I am also not sure what is causing it but crashing on all system (10.8/10.9.5/10.10 too) mostly on same line number.
In my system I have created a shared instance of EGODatabase and using it for all DB related operation from all three threads. Please confirm if it is fine or I need to change it:
. Below are crash threads:

And second is:

Any help will be appreciated greatly.
