GPT partition tables are not properly detected - Ubiquity suggests erasing disk

Bug Description

The Ubuntu installer detects 4 or more (primary) partitions during installation and suggests to erase the disk and therefore remove Windows (first option) instead of resizing the Windows partition and add necessary Ubuntu partitions (e.g. "Install along side" option, which is not displayed).

This may be caused by a missing check of the target systems partition table type (assuming that installation is not possible on a drive where there are 4 primary partitions, which is not true for GPT). Resizing manually and choosing installation option "Something else" works with 14.04.

The device used for testing was of the Toshiba Satellite NB10-A-10 (NB10-A-10N) model line with OEM preinstalled Windows 8. The issue was reproducable (restoring untouched from diskdump).
