[Lazarus] Problems with r29727

[Bart]

I just did a make clean all OPT=-gl, so range check is probably off
(it is off by default in fpc and I didn't change the fpc.cfg to put it
on).

I now managed (twice) to get lazarus to crash and create a debug.log.
(I can't get a backtrace in gdb, afthe the crash I have to kill
startlazarsu, and lazarus using the taskmanager before gdb becoms
responsive again, and the it denies thee was a crash in the firts
place. Yet another reason why I'm migrating to Linux <g>)

This is Lazarus crashing almost directly after starting it:

SetPrimaryConfigPath NewValue="h:\programmas\svnlaz" -> "H:\programmas\svnlaz"

F:\LazarusProjecten\UurCodes\main.ppTMainIDE.DoOpenProjectFile

  $0055749F  TCUSTOMTIMER__TIMER,  line 156 o

Both times I got the same output in debug.log, so the problem probably
is in GetDetailRegion in win32themes.pas, which was introduced in
r29642.

I now downgraded Laz to r29641 and the crashes seem to have gone.

I guess I'll have to file a report in Mantis?
