I am having the same issue. Here is the bug I submitted on bugzilla as I have been trying to work on this issue: http://bugzilla.gnome.org/show_bug.cgi?id=577361
I may be wrong as I don't know a lot about coding in c, but it appears it may be a timezone issue in the calendar entry. I can provide more as I am able to run this with debug symbols. I have also confirmed this issue exists in Evolution 2.26.1 compiled from SVN trunk as of tonight as I have been debugging this issue. ** Bug watch added: GNOME Bug Tracker #577361 http://bugzilla.gnome.org/show_bug.cgi?id=577361 -- evolution-exchange-storage: /build/buildd/libical-0.43/src/libical/icalerror.c:106: icalerror_set_errno: Assertion `0' failed. https://bugs.launchpad.net/bugs/353187 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
