[Gambas-user] IDE crash with commit e186a1b75 (TabStrip should not crash anymore with an undefined symbol)

[Bruce]

My IDE crashes with the following error when I access the help.

------------------------------------------------------
This application has raised an unexpected
error and must abort.

11] Unknown symbol 'Clear' in class 'WebView'.

MHelp.InitWebViewWith.448
---------------------------------------------

A similar error also happens if I have autocompletion turned on and I 
start typeing a keyword or symbol name etc.

Has anyone else experienced this (it might be a local error)?
