Version: 4.2.2 (using KDE 4.2.2) Compiler: gcc-4.3.2 OS: Linux Installed from: Gentoo Packages I experience this issue because I'm connecting to the Internet via ppp, so a non continuous connection. Every time I disconnect, after a while (the time to search for new feeds?) akregator crashes. Here's the backtrace (I'm sorry, it's in Italian). It says that it is an usefulness backtrace, but it has informations at its bottom. Regards, HUjuice Backtrace: Questo backtrace sembra essere inutile. Probabilmente i pacchetti che stai utilizzando sono compilati in modo che non si possano creare dei backtrace corretti oppure lo stack frame è stato danneggiato seriamente durante il crash.

What is your Qt version ? Thanks
Mmmh... maybe it is a Gentoo portage issue? I didn't see that I've qt-3.3.8b installed and (I don't know why) normal updates don't bring me to the available 4.4.2. Since all KDE is ok, I didn't see it. I'm upgrading now. You know that on Gentoo I'll compile everything, so I need a while. If you agree, we can keep this bug as "suspended" for a dozen of hours, the time to try again. Regards, HUjuice
The problem is still there. Now I have Qt 4.4.2 and in the last night I had an upgrade to KDE 4.2.3, including Akregator (1.4.2). And coming back home (Akregator up, Internet connection down), I've found the crash. I'm not a C programmer, but if you want I can recompile Akregator in a different way, to have more backtrace informations. Feel free to ask everything you want inside this guide: http://www.gentoo.org/proj/en/qa/backtraces.xml Regards, HUjuice
May you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Gentoo should have a guide about recompiling packages with debug symbols enabled. Thanks
Yes! It belongs to "my" Gentoo guide. I'm a bit confused now, here is what I'll do tonight: CFLAGS="${CFLAGS} -ggdb" FEATURES="${FEATURES} splitdebug" LDFLAGS="${LDFLAGS} -s" ("FEATURES" are Gentoo specific? I read that I should activate it here http://www.gentoo.org/proj/en/qa/backtraces.xml) emerge x11-libs/qt-core x11-libs/qt-gui kde-base/kdelibs sys-libs/glibc ("emerge" = "apt-get install", if you're unfamiliar with Gentoo) Then, I'll reproduce the crash (it happens always). If you have more suggestions, I'll follow it. Regards, HUjuice
