I have configured my quasselclient of =net-irc/quassel-0.10.0 to "Automatically connect on startup" so it shows directly the "Authentication required" dialog after startup so that I can enter my core account's password. Directly after hitting Enter resp. clicking OK, the quasselclient crashes: $ quasselclient Fontconfig warning: "/etc/fonts/conf.d/59-google-droid-sans.conf", line 61: Having multiple values in <test> isn't supported and may not work as expected Fontconfig warning: "/etc/fonts/conf.d/59-google-droid-sans.conf", line 96: Having multiple values in <test> isn't supported and may not work as expected No DockManager available Enabling compression... Using the DataStream protocol... Starting encryption... [1] 28415 floating point exception quasselclient I will attach a stack trace of this crash. Reproducible: Always Steps to Reproduce: 1. Configure quasselclient to automatically connect to core w/o password set. 2. Enter password in authentication required dialog and hit enter. Actual Results: quasselclient crashes with floating point exception. Expected Results: Should not crash, of course. I found this workaround for now: 1. Run quasselclient. 2. Click "Cancel" on "Authentication Required" dialog. 3. Manually select "Connect to core" from menu. 4. Enter password, click "OK", and no crash occurs. $ emerge --info quassel Portage 2.2.10 (default/linux/amd64/13.0/desktop/gnome, gcc-4.8.2, glibc-2.19, 3.13.7-gentoo-vidar-amd x86_64)

Created attachment 374536 [details] GDB backtrace of quasselclient crashing with floating point exception.
So that's mildly amusing. I do wonder if you can reproduce it without the nvidia driver :)
(In reply to Patrick Lauer from comment #2) > So that's mildly amusing. I do wonder if you can reproduce it without the > nvidia driver :) Actually, I can reproduce it also on a system running on Intel graphics. It also crashes, with the same backtrace.

Can confirm. This is a legitimate floating point exception - you are taking a modulo by zero :) Program received signal SIGFPE, Arithmetic exception. 0x00007ffff7396884 in QCleanlooksStyle::drawControl (this=0xacc040, element=<optimized out>, option=0x7fffffffad00, painter=0x7fffffffb4f0, widget=<optimized out>) at styles/qcleanlooksstyle.cpp:1777 1777 int step = ((d->animateStep * slideWidth) / d->animationFps) % slideWidth; (gdb) p slideWidth $1 = 0 CC-ing qt team since at first glance this seems like a bug in qtgui's QCleanlooksStyle engine.
Created attachment 374890 [details, diff] patch for qtgui-4.8.5-r1 Simple patch for qtgui, fixes the crash for me.

Thanks Alexandre! Patch applied in qt overlay, will be moved to the tree together with qt-4.8.6
Fixed in 4.8.5-r3
