[ubuntu-mono] [Bug 433817] Re: Gnome hang when dragging starters to docky

[Patrick Rynhart]

I have experienced this Issue with Lucid.  I'm only able to drag one
item to the dock before then needing to exit Gnome-Do - otherwise
dragging a second item will cause this lockup of the GNOME desktop.

Status in “gnome-do” package in Ubuntu: Confirmed

Bug description:
I was dragging launchers between nautilus-desktop, gnome-panel and gnome-do (Docky mode) when I got the error "Drag and drop is not supported. An invalid drag type was used."

I can still move the mouse pointer so it doesn't seem to be a kernel panic. I can press "caps lock" and see the "caps lock" light come on, so basic I/O is still there.

The system isn't hung exactly, but nautilus-desktop and gnome-panel are not responding at all to left, right and middle clicks. Neither is gnome-do responding to clicks but it still does the "dock zoom" whenever I mouse over it.

The error dialog is still on the screen. I can't get rid of it. I can't click the "&OK" button, pressing Alt-O doesn't work either. The mouse pointer is stuck in "drag" mode.

I have to restart X in order to make my desktop useable again.

-----------------------

workaround: switch to terminal (ctrl-shift-f1), log in, execute "killall gnome-panel", log out (ctrl-d), switch back to x (ctrl-shift-f7 per default)
