Reader Error after update from svn

I updated yesterday both FPC and Lazarus to latest svn releases
(Lazarus again 5min  ago). Now I can compile my project without any
problem but it fails to start with some weird exception "Error reading
<Trackbar>.Position: Access violation." If I debug that it leads to
TCustomForm.Create->InitResourceComponent(Self,
TForm)->InitLazResourceComponent->Reader.ReadRootComponent(Instance);
(LResources:3043). There is no error on initialization all other forms
except this one which has as configuration dialogue with a lot of UI
elements including some trackbars. Removing *.lrs did not help. If I
create a new application and place a trackbar there it works fine.
Any idea how to solve?

How does the <Trackbar>.Position look like in .LFM file?

I can move trackbars around at designer, copy/paste - no error. It
compiles also well but crashes on initialization. It was recommended
to me to change resource setting for the project from lrs to fpc. I
tried this but had no success.

I have no idea why but the error disappeared. First, I removed all
trackbars - success, then I replaced - error. Second, I moved all
trackbars to a new tabulator at the pagecontrol - no error, and moved
back - still okay. Very strange!
