Public bug reported: I had two windows running in LibreOffice - the document window and the bibliographic entry window. When I tried to select the document window from the Gnome3 launcher, the desktop froze - no mouse movement, no keyboard. After about 1 minute the Gnome 3 session restarted. This message in the log file:
