IDE crash with Property editor popup

Type             : Bug
Priority         : Low
Gambas version   : 3.8.90 (TRUNK)

Description
-----------

Following causes the IDE to crash (confirmed by Jussi in rev 7333)

1) Open any GUI project in the IDE and load a form (the form itself should be selected)
2) Double click on the Text property (The Edit text property popup is shown)
3) Close it using the window manager X button N.B. not the Cancel button on the popup 
4) Double click on the Name property (The Edit text property popup is shown)
5) Again, close it using the window manager X button

--->

This application has raised an unexpected
error and must abort.

[13] Null object.

(N.B. The line number above may not be correct for the trunk - I am using a local version of the IDE)
