[SOLVED] Qt Creator - GUI Builder Won't Start

[Ade Malsasa Akbar]

Any project I create, any project I open, if I am trying to open mainwindow.ui (open GUI Builder), the Qt Creator closed directly unexpectedly. I don't know why, but my Qt Designer also has same problem when I start it. Here is the important additional informations.

My specification:

• Ubuntu 12.04

• KDE 4.10.3

• Akonadi 1.11.0

• Qt Creator 2.4.1

• Qt 4.8.1

My error messages when I start GUI Builder on Qt Creator via Konsole:

My question:

• What is actually my problem?

• What is the solution?

Thank you so much.

Hello, is there any suggestion? Thank you.

Alhamdulillah, it solved by removing libpimcommon4 package from Ubuntu anyway. I just simply remove conflicting repo (Kubuntu Backports) then do

@sudo apt-get remove libpimcommon4@

(it removes also my KNotes but I can install it later)

This is the proof of solution. Now my GUI Designer in Qt Creator can be opened normally like before. And my Qt Designer is normal again, no crash. My problem was finished.
