I have found a reproducible crash, at least on my computer. I do not know if LyX is at fault, or XForms, or anything else.
The recipe : I open LyX, go directly to Edit->Preferences->Language->Language, open the box to choose the language (arrow on the right). Then I change the virtual desktop of my window manager (metacity-2.4.0.92-5, default on RH 8). The box with the languages follows me, even if it should not. Then I click anywhere on the screen outside the box, and LyX disappears saying only this : >/opt/bin/lyx -dbg all Niveau de débogage all LyXComm: Pipe /home/rebollo/.lyxpipe.in already exists. If no other LyX program is active, please delete the pipe by hand and try again.BadMatch (invalid parameter attributes) id: 41943207 Abandon I have the same story with every XForms "arrow box", such as Layout->Document->Document Class. The only difference is the BadMatch id number. My system is a RedHat 8.0, and I use Gnome shipped with Redhat.
