nepomukservicestub crashed with SIGSEGV

[Brian Buchanan]

Binary package hint: kdebase-runtime

This crash warning appeared when I left my computer on over night in the gnome session.
I have both gnome and KDE desktop environments installed.

No applications were running apart from Thunderbird and Empathy.

Thank you for your report!

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might be caused by some outdated packages which were installed on your system
