Version: (using KDE 4.2.0) Compiler: GCC 4.3.2 Target: x86_64-unknown-linux-gnu Configured with: ../gcc-4.3.2/configure --prefix=/usr --libexecdir=/usr/lib --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++,fortran,objc,treelang --disable-multilib --enable-c99 --enable-long-long Thread model: posix OS: Linux Installed from: Compiled From Sources I've upgraded to Qt 4.5 beta 1 and found that notifications from Kopete didn't work anymore with this version. With Qt 4.4.3 it worked fine. From Dolphin notifications (when copying file etc.) also work. Although 4.5 isn't final release now, maybe this report will be useful.
Same here on Gentoo
Fixed with Qt 4.5 final and KDE 4.2.1 (don't know where exactly, I've updated it together).
Thank you for your feedback. Closing this report.
