LyX crashes when copying from one doc to another

[Mario Mommer]

Hi, I'm using lyx 1.2.1 w. xforms 0.89, and I observed the following bug:

I open a new document and type "whatever"

I open another new document

I go to the old one and mark something. Then I type C-C

I go back to the second document. It faints

Here's the backtrace.

Regs,
        Mario.
