Caonnt confirm with current SVN branches/KDE/3.5/kdesdk/umbrello. It would help if you could: 1) Describe the last few actions that you did before pressing Ctrl-Z 2) Invoke the "configure" script with --enable-debug=full so that we see line numbers in your backtrace Thanks.
I seem to be getting the same kind of crash with the same output, in Umbrello 1.5.8 (Using KDE 3.5.9-5.fc8) on Fedora 8. The bug appears in every default view, when you 1) add a component, that does not show a dialog box (eg association, box etc...) 2) right click the view field, so the cursor returns to the "select" state 3) ctr-z to undo Tried it about 10 times in different views, works every time.
Umbrello crashes everytime when "undo- stack/array" is empty! It definitely do not depend on kind of diagram, because I can reproduce the crash every time by: Class-, Use-Case-,..., and last but not least Entity-Relationship- Diagram! It seems to me that the problem is a function call without checking if the data-structure (which contains the done last actions) has any elements, which produces a Null-Pointer-Exception/Error.
