After updating maintenancetool (MT) it reports:
„Your installation seems to be corrupted. Please consider re-installing from scratch.”

Steps:
1. Start maintenancetool. It will want to update itself before updating other packages. Press next and it will update and restart by its own.
2. MT will report the corrupted installation message. If we ignore the message and go to "Update component" the message is: „Failure to read packages from /home/user/Qt/components.xml”.

This message is not correct, since the installation path is /home/user/exec/Qt2, and it actually contains a component.xml file.

It has happened with the previous upgrade, and happened after upgrading to 2.0.1 too.
