Is there a way to merge two (or more) versions of the file el-v1.db?

I have previously backed up an older version of this file, about two weeks ago, and I deleted that file (so the system can create a new one) just to have a working logging facility. It was due to the conversations bugs (I'm sorry, I forgot the bug IDs) related with PR 1.3, wherein:

1- New messages, be it SMS or IM, are not logged, i.e., the file /home/user/.rtcom-eventlogger/el-v1.db is not updated

2- The Conversations app does not display updates when receiving or sending messages
