Andrea,

Thanks for the dump.  I hope GG can figure this out this time.  If you happen to be running with "gdb", the next time this happens, at the gdb prompt you should see on your screen, type in:   bt

and tell us what that reports.  "bt" stands for back trace and shows about 6 lines of program code so that gg can see where it crashed.  This is also useful when Cinelerra hangs up without crashing which in that case if you are running gdb, you can do a "Ctrl-c" in the window where gdb was started and type in "bt" to see where it is hung up.   These are extremely helpful in locating the problem.     Phyllis/gg
