I don't know the fix for this but at least I know a workaround:
1. Move away your pinball.xmi so that umbrello no longer autoloads it
   on startup
2. Start umbrello, go to the Settings->Configure Umbrello menu,
   deselect "Use tabbed diagrams"
3. Exit and restart umbrello

kde backtrace of umbrello crash at exit

I can confirm this bug with umbrello 1.4.92. see the attached KDE crash report.

Comment 4 Piotr Kubowicz 2006-05-10 16:17:19 UTC

Confirm with umbrello 1.5.2 and KDE 3.5.2.

Comment 6 Piotr Kubowicz 2006-05-10 16:24:43 UTC

BTW, in my case attached (pinball) model causes crash at start. I have created another model (rather simple) which also causes crash, but at exit (nearly every exit). Turning off tabs does not change anything (except that it is easier to cope with many diagrams).

Output to console produced by Umbrello at crash when opening a file.
