Prakash, Could you please confirm that this bug is still present? If so, can you explain how to reproduce it?
Created attachment 37199 [details] Crash backtrace
I could reproduce the crash now, the list was showing "4,294,966,847" objects to be added. I just kept clicking update count at each step. And when I clicked on okay, I got the crash. I've attached the backtrace.
I can confirm the crash. Will investigate soon.
SVN commit 1169737 by mutlaqja: Fixing a crash in observing list wizard due to over-decrementing objects by the filters. Since this was an unsigned integer, it rolls back to a value of about 4,294,966,847 and causes a crash. I updated the wizard to be much more efficient in elliminating targets without putting heavy load on the system. Furthermore, I added a time limit range as suggested by Fabien to limit the observing period.
