cannot edit ebook after ubuntu update to 16.10

[emddom]

After upgrading to Ubuntu 16.10 (from 16.04) I can't edit ePub files any more.

I receive unhandled Exceptions (please see attachment) when I select a *.html file for editing.
(interestingly, I receive a similar error when using (Nautilus) file manager and clicking on "Recent Files")

My Calibre version is 2.60

With best regards,

Please select "Copy to clipboard" when the error message shows up, and
paste it here directly.

Submitting error messages in a text file or word document requires
invoking external programs just to read, and word documents are beyond
ugly and vastly unnecessary for this purpose. Using a screenshot of the
message is possibly the least accurate and most unreadable way of
passing along TEXTUAL INFO that mankind has invented, but people do it
depressingly often.

In other words, please don't use attachments for error messages.

...

Also, Ubuntu 16.10 currently ships calibre 2.60.0 in their repositories,
but the latest version of calibre is v2.72.0 so can you please confirm
whether you simply haven't upgraded in a few weeks or whether you are
using the distro package?

Using the distro package is a common source of problems, and if the
problem cannot be duplicated with the official binary releases on
calibre's website, then it is a distro packaging bug and you should ask
the Ubuntu packagers for help.

If you simply haven't upgraded in a few weeks, then 1) interesting
coincidence :D and 2) try upgrading to the latest version of calibre
anyway, to make sure it is still a problem.

  Hello Eli,

Thanks for the email and the swift response.

I'm (almost) sure that I put the attachment....
And you're right: textual format is better (The notice: "Copy to clipboard "
skipped my attention)

Here it is as text (I cannot use Copy to Clipboard any more due to yet
another bug... :) )

After submitting this bug report I did make the update to 2.72-0 using the
command line.
But now I cannot use Calibre at all. Doesn't matter whether I start up
Calibre from the command line or from the menu.
If I start from command line then I get several times this message:

(calibre:9244): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion
'GTK_IS_WIDGET (widget)' failed

About this I complained in the following bug report:
https://bugs.launchpad.net/calibre/+bug/1643815

To test, I did the same Calibre installation/update on Ubuntu 16.04, which
I run on a Digital Ocean server. There it works all fine, including the
eBook editing. So, it's my HP Elitebook with Ubuntu 16.10 where I have all
these difficulties.

I have to admit that I have been fooling around with various desktops on
this machine, because of problems when trying to use the HP machine as VNC
server and a Chromebook as a VNC client.
However, I had no other issues, except for eBook editing (and the Recent
Files issue when using Nautilus)

  With best regards,
     endre

Uninstall the distro provided calibre and install the official calibre binary and this error will go away.

  Hello,

Sorry. I thought that I've already answered "back then" when the problem
got solved by using the default "look":
Ever since it's worked fine, even after having updated to the latest
version.

  Thanks and all the best,
    endre
