I can reproduce this. Multiple stacktraces show that the error does not always occur at the same place but is always related to tile memory. I have carefully checked the latest changes to app that might cause the problem: app/pixel_region.c 1.20 app/paint_core.c 1.90 app/paint_core.h 1.30 app/undo.c 1.60 and couldn't see any problems. I could reproduce the crash after reverting all those changes, so it seems the problem is elsewhere. Salut, Sven
