Qt designer freezes after opening dialog [SOLVED]

@mrjj
Thank you for investigation. It may be the problem with VM, but I am not the person who manages it. Can it be the problem with Qt Creator config? If yes, what files should I look for?

Well it seems to be a problem with QT Creator since the xml file seems valid and can be loaded in both win and linux.

So I assume something wrong with the Creator installation.

I am not aware of any config that would affect the reading of UI files as it is
a integrated part of Creator.

Would it be possible for you to create a snapshot of the WM and then reinstall qt?

I have to ask administrators of the VM if it is possible. Many thanks for your time.

It is possible to install qt with no root access

You could install a new qt to a new folder in /home and run it from there but to be on the safe side,
it is best to have a backup of what you have now.

One question.
If you make a new UI file and then insert control to it, it will also start to crash Creator ?

I created new UI form and could modify it without problems (eg. add buttons). However when I put the xml code from previous dialog freeze occurred again - so I suppose something is wrong with this form's nodes.

Just strange that the same xml works fine here.
But I guess if you can just recreate the dialogs and it works, it a fix.

I have found what was the real problem. This issue occurred only on Dialog windows. I set for them 'modality' - ApplicationModal and that was the problem I was looking for. After removing this property from xml file everything is fine.
It seems to be a bug.

Nice found!

Not sure where in the shown xml this is ?

remember to flag as solved :)

After removing property "windowModality" freeze is not occurring again

<ui version="4.0" >
 <class>CreateExecutionDialog</class>
 <widget class="QDialog" name="CreateExecutionDialog" >
  <property name="windowModality" >
   <enum>Qt::ApplicationModal</enum>
  </property>
  <property name="geometry" >
...

System: CentOS 5.5
QT version: 4.2.1
