Confirming the problem.

Gutsy tribe 3 fresh install on Lenovo T61

Can't remove either panel without a crash.

Thank you for your bug report. I can confirm this with Tribe 5 fully updated, I'm marking as triaged and will report upstream.

[Jérôme Guelfucci (jerome-guelfucci-deactivatedaccount)]

Setting importance to high.

[Lionel Le Folgoc (mrpouit)]

Just fixed in upstream svn. I'll test and upload a fixed package.

I can confirm this on an Archlinux (don't panic) running kernel 2.6.22 with xfce 4.4.1
