+Subject: [PATCH] app: fix #8120 GIMP 2.10.30 crashed when allocate large
+ memory
+
+GIMP could crash if the information regarding old path properties read
+from XCF was incorrect. It did not check if xcf_old_path succeeded and
+kept trying to load more paths even if the last one failed to load.
+
+Instead we now stop loading paths as soon as that function fails.
+In case we have a failure here we also try to skip to the next property
+based on the size of the path property, in hopes that the only problem
+was this property.
+
+(cherry picked from commit 4f99f1fcfd892ead19831b5adcd38a99d71214b6)
+
