I just tried the example I'd posted before and now it works correctly.
Unfortunately, it seems that something else broke (or something broke on my
system while upgrading from RC1 to the 4.5 branch). However, as soon as I try
to create a KDE::AboutData object.
The code I use is the following:
require 'korundum4'
KDE::AboutData.new 'test', 'test', KDE.ki18n('Test'), '0.0.0'
It worked with korundum from RC1, but now I get a crash with the following
backtrace.
