virtualbox.org

Host: OpenSuse 11.3 64 Bit, KDE 4.5, VBOX 4.0 b2.

If i try to change the guest via button or contextmenu, the gui crashes always. Message in xterm: "Speicherzugriffsfehler" (Memory Protection Error).

Call the setup window by clicking on a special link like audio in the right guest settings area works always.

Cannot reproduce. OpenSUSE 10.3 amd64 but Qt on this system is currently at version 4.6.3 -- is your host up-to-date?

Nore than up to date.

KDE 4.5.x and qt 4.6.3.

Ah right. But still, unable to reproduce. Does this happen with every VM or only with one VM?

Every VM. As i said: Opening over the links works, its the same dialog and all is working.

Tried reinstalling VB? I also see different versions noted, Stefan has problems with 11.3, Frank says he's using 10.3. Which OS are you using?
Stefan, if you run VB from the terminal, what does output do you get when VB crashes?

Sorry, 10.3 was a typo, I actually meant openSUSE 11.3.

The error is "Speicherzugriffsfehler" (memory protection error).

Yes, but I have to be able to reproduce this. Or can you provide a core dump?

Do you know a way to save such a file?

I have not found one i home, tmp, var/tmp.

I found a way to produce core files, It works as suggested with the bash-kill. But for VirtualBox there is no core file, sorry.

Did you read this article?

No. After reading i have a core file, but its about 38 MB. Im uploading the file to ifile.it. Will post the link later.

Here it is.

Investigating. Btw, which KDE style do you have installed?
