Nokia QtSDK installer crash on Ubuntu: how to fix it
HowTo, Linux, Programmazione, Qt, Ubuntu (EN) Add commentsIf you try to install Nokia QtSDK on Ubuntu using the Nokia installer (that provides a newer version than the one distributed in Ubuntu Software Center) you could get an error like this:
(Qt_SDK_Lin32_offline_v1_1_3_en.run:3126): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed
to fix it, you need to run the installer with a specific parameter:
andrea@centurion:~/Downloads/Qt$ ./Qt_SDK_Lin32_offline_v1_1_4_en.run -style cleanlooks
and everything should work!

For me the problem was not the message you pasted (I see these, or at least similar ones, all the time), but a huuuuuge memory leak that would make my machine slow down to a crawl. The same fix applies.

@Marius: a problem remains… you cannot use the updating tool available in QtCreator. I’ve tried starting qtcreator with the same parameter, but it doesn’t start the updating tool anyway. This is a weird problem!

@Andea: you proble fixed by change interface style in qtconfig-qt4 from gtk to another.
yes we have some workaround, but this not good. My IMHO is program developed or usage Qt Framework, QtSDK, QtCreator must be work on ubuntu with Unity out of the box!
Probleb (segmentation fault, freez comp, don installed chinas font ( ? ) …)with program developed on Qt framework is started from Ubuntu 11.04 . But bugreport dont’s resolved

@MSergey: yes, using qtconfig-qt4 and setting the style to “Cleanlooks” affect the settings in a more generic way. In this way you can also start the Sdk Updater and it works
