The one reported by Alan Mead is reproducible and it should stay open till it is fixed.
The one reported by Robert Gross seems to be only reproducible by Robert. Without further info, it can't be fixed.
I am working on a version with GTK3 which has an option to start psppire in gdb from the MSWindows start menu. The user has clicke it and then type "run" in the command prompt and then the psppire gui starts. When crashing, the commandprompt-window will give more info and it might be possible to do a backtrace.
I still need to write a few lines on how to use gdb.
