Doc Text:
Programs no longer run out of memory when repeatedly listing available *polkit* actions Previously, the *polkit* client library did not correctly free memory when listing available actions, which could cause programs to run out of memory and terminate. With this update, the library frees the memory correctly, and programs no longer crash in this scenario.
