[lazarus] Memleak caused by gtk keyboard tables

[Vincent Snijders]

Hi,

Lazarus has some memleaks caused by the keyboard tables. I have tried to
look into it, but it looks a bit to complicated to me. It is probably 
not a critical bug. This table seems to be set up at application start,
used during the lifetime of the application, but is not (completely)
freed at the end. See heaptrc at the end of this mail for some details.

An other thing I noticed, is the comment with TGTKObject.AppInit.
  (is called by TApplication.Initialize which is typically after all
   finalization sections)
I don't understand this. What finalization sections are meant?

A third thing: The text in the BuildLazarusDialog is unreadable, because
text and backgroud are black. Has anybody else noticed this?

Regards,
Vincent Snijders.

The heaptrc log is:
