[Lazarus] the options window crash

[ik]

Hello,

I'm trying to register a new section for the key shortcut option:
https://github.com/ik5/split_lazarus/blob/master/src/untlazsplitview_code.pas#L42

Lazarus has the following exception because of it:
TApplication.HandleException Access violation
  Stack trace:

Lazarus 1.1 r40007M FPC 2.6.0 x86_64-linux-gtk 2

What am I doing wrong here ?

Thanks,
