Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

outdated debug symbol package for libgirepository-1.0-1: package version 1.42.0-0ubuntu1~utopic2 dbgsym version 1.41.4-0ubuntu1
outdated debug symbol package for libgnome-desktop-3-10: package version 3.14.1-1ubuntu1~utopic2 dbgsym version 3.12.2-2ubuntu1

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

I also think that this bug/crash report should be moved to ppa:gnome3-team/gnome3 as it relates to GNOME 3.14 on Ubuntu 14.10.

Similarly, when I try to access an application menu (e.g. in gnome-terminal -> Edit), a similar crash happens.
