    Following steps to reproduce:
    1) open inkscape
    2) In Menu, select: Text > Text and fonts..

    The dialog window is shown, at the same time the error message appears, saying that inkscape will close now.

    Emergency save activated!
    Emergency save completed. Inkscape will close now.

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might be caused by some outdated packages which were installed on your system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:

libnspr4 version 4.8.9-1ubuntu2.3 required, but 4.8.9-1ubuntu2 is available
outdated debug symbol package for initscripts: package version 2.88dsf-13.10ubuntu13 dbgsym version 2.88dsf-13.10ubuntu11.1
outdated debug symbol package for libecryptfs0: package version 100-0ubuntu1 dbgsym version 96-0ubuntu3

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!
