Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at: http://bugzilla.xfce.org/show_bug.cgi?id=6213

The upstream developers believe this is fixed in libxfcegui4 4.6.3, which is in Lucid Lynx.

The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . It can be downloaded from http://cdimages.ubuntu.com/xubuntu/daily-live/current/ . Thanks again and we appreciate your help.

Crash occurred during ISO image testing of the Release Candidate for Xubuntu Lucid. Reported to developers at Xfce.

[A. Denton (aquina)]

It also happened when testing [L1]. I marked the bug as serious in iso.qa.ubuntu.com since this happened the third time to me now and I think it is a severe drawback for Xubuntu users.

Should be fixed in natty (Xfce 4.8~pre1).
