update-mime-database crashes on incorrect mime definition

Binary package hint: update-manager

When upgrading from Edgy to Feisty. I get these errors:

It's actually not a problem with update-manager. The problem is with shared-mime-info configuration. I have to rewrite /usr/share/mime/packages/freemind.xml

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
        <mime-type type="application/x-freemind">
                <comment xml:lang="en">FreeMind Mindmap</comment>
                <glob pattern="*.mm"/>
        </mime-type>
</mime-info>

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Sebastien Bacher (seb128)]

what is the interest to tag a shared-mime-info bug with the name of the package?

[Prem Rara (fortran01)]

How do I actually run the shared-mime-info binary to get the backtrace?

Btw, freemind is a custom install. The installation did not go through because the syntax of the xml file is wrong (I think). This is the original file:

<mime-info>

 <mime-type type="application/x-freemind">

  <comment xml:lang="en">FreeMind Mindmap</comment>

  <glob pattern="*.mm"/>

 </mime-type>

</mime-info>

I changed it to:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
        <mime-type type="application/x-freemind">
                <comment xml:lang="en">FreeMind Mindmap</comment>
                <glob pattern="*.mm"/>
        </mime-type>
</mime-info>

What I actually mean is: the install/upgrade of shared-mime-info package did not go through because the syntax of the xml file is wrong (I think).

The incorrect xml makes it crash, I've opened the bug upstream: https://bugs.freedesktop.org/show_bug.cgi?id=10959

[Christian Neumair (chris-gnome-de)]

Thanks, I replaced the calls to g_error() with calls to g_warning().

[Sebastien Bacher (seb128)]

the bug has been fixed upstream now
