[lazarus] bject inspector do not appear

[Daniel Hagemeister]

I use the most current versions of lazarus and FPC (development tree).
If I start lazarus, then everything works quite well.
But object inspector do not appear. It cannot be started also over 
the menu. in xterm appears a long lines up from messages how:

..
..
..
Gtk-CRITICAL **: file gtkfixed.c: line 175 (gtk_fixed_move): assertion 
`GTK_IS_FIXED (fixed)' failed.
[TBitmapCanvas.CreateHandle] Got Handle 0x81185B4
[TBitmapCanvas.CreateHandle] Got Handle 0x8118284
[TBitmapCanvas.CreateHandle] Got Handle 0x810D104
..
..
..

 I use suse 7.0, FPC and lazarus from the source texts compiled.
 what can i do to correct the bug?
