Hi Vadim and wxWidgets people,

I made a small Destroy function in my TaskBar-class which looks like
this and call it instead of directly using delete:

void TaskBarIcon::Destroy ()
{
	wxPendingDelete.Append (this);
}

It works fine for me, but I don't know if this is the whole trick or
if there may araise any problems with other stuff. If anyone can point
out if this is enough (it does the trick for me ...) so I can work out
more details and finally create a patch.

Regards,
Chris
