[SanityIO at orion bin]$ ./qtcreator
Object::connect: No such signal

Segmentation fault

Here is how i crushed it:

	*  [$] ./qt_creator
	* in welcome screen selected recent project to open
	*  (left panel double click) open any cpp file in project
	*  (left panel double click) opened ui file of dialog
	* at the designer object tree (right panel) double click on
		 anything (layout or object) so that it goes to edit mode
	* at the opened for edit files combo box select previously opened
		file.
	* at the opened for edit files combo box select previously opened
		ui file.

90% of times segfault happens.
If it didnt happen try to select another object in object tree (in designer) 
and select cpp and ui again.

Hmm...
Another simple scenario to crush:

	*  [$] ./qt_creator
	*    create new project. (for example "test" project)
		File->new-> Qt4 Gui app ->
		select a folder and name
		... next next .. all the defaults

	* File->New-> C++ class
		Name a class MyClass (with no base class)
	  and make sure it is added to test project.
	  
          As the MyClass.cpp and My class.h generated
	  creator autoopens myclass.cpp (Note: it the first thing opened in 
		project in to edit)
	 Do not edit anything..
	* Just double click in left panel on mainwindow.ui

and this gives a segfault.

Hmm maybe both segfault related to same thing:
opening ui and custom class cpp.


Best regards :)
