I am running Version: 4.2.3.3 Build ID: 420m0(Build:3) using Ubuntu 14.04 operating system.
Received this message when trying to insert rows in existing spreadsheet (which has worked for years). Crashes after msg rcvd. Have to restore. Reported this some time ago. Believe it was Bug #78353. Have received no response on how to repair condition. If this is something I cannot do, would like to know it is being worked on.
