+Subject: [PATCH] Use lazy imports in abrt_exception_handler3
+
+The abrt_exception_handler3 module is always imported when Python starts,
+but all the modules imported from it (except sys) are only used during crashes.
+
+Especially the systemd.journal import is really expensive.
+
+Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2007664

-Subject: [PATCH] hooklib: Proper freeing of backtrace
-
-Improper bracing caused the bt variable to be freed every time in every
-iteration no matter what. This would then lead to an invalid (freed)
-pointer being returned by the function.
-
-The mistake was made in 1f2963b0 and reported by Jeff Law.
