Version: 4.1 (using 4.1.4 (KDE 4.1.4), Gentoo) Compiler: x86_64-pc-linux-gnu-gcc OS: Linux (x86_64) release 2.6.26-tuxonice When a script set up as hook fails with an exit code > 0, there is no feedback. (Note that I have only tested this with the SMS hook.) There should at least be a warning message that the script failed. The best solution would be capturing the script's stderr additionally.
Well, you can wrap the script into something that calls kdialog as a workaround.
The development of the old KAddressBook will be discontinued for KDE 4.4. Since the new application has the same name, but a completly new code base we close all bug reports against the old version and ask the submitters to resend there reports against the new product.
