[Lazarus] Unable to stream selected components! TIdSimpleServer

[Bo Berglund]

I have FPC 3.0.0 and Lazarus 1.6RC2 installed on an RPi2B platform
running Raspbian Jessie (latest).
In Lazarus I have installed the Indy 10.6.2 components from code
downloaded by svn (trunk) yesterday.

Now I tried to use them for the first time by starting a new project
and then selecting the tab "Indy Servers - Core", clicking on the
middle icon (TIdSimpleServer).
Next I clicked in the form that was displayed by Lazarus in order to
place the component there. Up pops a message with a red stop sign:

"Unable to stream selected components
There was an error during writing the selected 
component IdSimpleServer1:TIdSimpleServer:
Access violation"

When I click OK the message goes away and the component is present on
the form.

I have not seen such a message earlier and it will not happen if I
drop any of the other components on the same tab onto the form.
As expected it does not happen when I drop standard components like
TButton and the like either.
It seems to be tied only to this TIdSimpleServer component, which of
course is the one I want to use and the reason I installed Indy10 in
the first place...

Any ideas?
