[Bug 59240] update-mime-info segfaults

[Daniel Milstein]

Public bug reported:

Binary package hint: shared-mime-info

When I try and install shared-mime-info in apt-get, I get a segfault
with the following error message:

Setting up shared-mime-info (0.17-0ubuntu11) ...

Is there anything that I can do to fix this?

Many thanks.
