You will find four crash reports in a short period of time from my IP just a few minutes ago.
One possible cause is that the account being monitored is on a Lan'd pc, and the log file size is now 104MB. I have set GINA to auto backup files at 100MB, but it may be that the backup only works on the main PC on which GINA resides and I just never noticed that to be the case. So it might not be a bug, exactly.
In any event, I deleted the log file, restored monitoring to the character, and cast a spell without crashing anything.
