[Qt-interest] QUiLoader's method "load" used in custom widget results in "Segmentation fault" in Linguist

QUiLoader's method "load" used in custom widget results in "Segmentation
fault" in Linguist

Hi !
I'm writing an interface program and it came time to internationalize it, so
I started reading the Qt Documentation. I was happy to see that all forms
loaded by QUiLoader are automatically translated, but I stumbled on a
problem. Almost the whole interface consists of custom widgets that are put
in the forms from designer. Some of the custom widgets use their own forms
that they load using QUiLoader class and here the problem appeared. When I
start Linguist and choose a translation that is located on a form that uses
some of my custom widgets the program ends with "Segmentation Fault". I put
a lot of prints to see where Linguist dies and I fount that when I invoke
the method "load" from class QUiLoader with valid ui file the application
dies. If the file isn't valid it doesn't die. I'm not sure if this is a bug
or not so I'm posting it here.

I made a simple example showing the problem.

P.P. I forgot to mention that I use Qt 4.7.0 because it comes with SDK that
is compiled with the same version. I tried using the new one but in my
custom widgets I use things like SQL and OpenGL and some more and designer
complains that cannot mix 4.7.1/4.7.2/4.7.3 with 4.7.4. I can workaroung the
problem with the enviroment variable LD_PRELOAD but it I don't like this
solution.
