I tried build 03-02 and the latest sources from SVN and both have the problem
described by mym. I tried running GtkRadiant in GDB and got two stacktraces that
show where the problem comes from:

Line 1013 in radiant/entityinspector.cpp is causing the Problems, which does a
simple gtk_tree_view_scroll_to_cell call. I'm not a GTK+ expert, so I just fixed
my local copy by commenthing out that line as it does nothing critical but
scrolling the tree view of the entity inspector.
