Whoops. We've just found out this indeed a bug.

In qmake terms, there's only 'KI18n', but no 'I18n'. qt_KTextWidgets.pri 
incorrectly references 'I18n', though.

Here's the fix:
http://quickgit.kde.org/?p=ktextwidgets.git&a=commitdiff&h=b83617d59b14941b1e26d295e9ea300301365321

You could apply the patch locally and be fine.

Thanks for reporting.
Cheers

PS: @devs: We should have really used the 'KF5' prefix for all qmake module 
names here. Now there's an inconsistency in the naming scheme for the modules.

Compare:
  KF5::Attica (CMake) - Attica (QMake) vs.
  KF5::I18n (CMake) - KI18n (QMake)

To fix and to avoid SIC we could generate/install an additional set of .pri 
files for KF5 which prefixes every module with 'KF5'?
