Qt SDK 2010.05.1 for Linux released

After the 2010.05 release of the Qt SDK, which accompanied Qt 4.7.0, we got word that Creator and the apps created with the packaged Qt would not look native on Gnome. This was caused by a missing GTK style plugin, which caused Qt to fall back to the non-native CleanLooks style.

The now released 2010.05.1 packages address this specific issue. Qt SDK 2010.05.1 is thus only available for x86 (32-bit) and x86_64 (64-bit) Linux environments.
