I see this in Ubuntu Gnome as well with 15.04. Double-clicking the Start button causes it to crash immediately with the SIGFPE, Arithmetic exception. Single clicking start, causes the application to crash a few seconds later, with everything still functional (not hanging).
I also used apport-bug and upon using the relaunch option, and then clicking start, Wallch behaves correctly. Stacktrace attached. ** Tags added: vivid ** Attachment added: "gdb session for wallch" https://bugs.launchpad.net/ubuntu/+source/wallch/+bug/1310776/+attachment/4292084/+files/gdb-wallch.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310776 Title: wallch crashes when started for the first time after click on Start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wallch/+bug/1310776/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
