Searchbuilder crash in 5.1.0
I built a search using Searchbuilder with 2 search lines. The first selected a group, the second selected a contact ID that was not equal to a certain value. I tried 2 different 5.1.0 systems that I maintain, and also the demo system at https://drupal.demo.civicrmfr.org - all crashed the same. Traceback is attached here... searchbulder.txt
