What were you doing when this happened?

Can you duplicate the crash?

Comment 15 Jonas Kantic 2016-02-07 11:09:13 UTC
Hi,

I exported my bookmarks from FireFox to a html-file and imported them
into Midori.
FireFox has two special bookmarks: "Recently bookmarked" and "Recent Tags".
As I am from Germany, these bookmarks are in german
in my FireFox: "Kürzlich als Lesezeichen gesetzt" and "Kürzlich verwendete
Schlagwörter".

The crash has to do with these bookmarks.
I can reproduce the crash with the following steps:

(1) Open Midori.
(2) Delete all current bookmarks in Midori.
(3) Select "Import bookmarks" and import the "bookmarks_bug.xbel" file
that I uploaded (this file has the two special bookmarks from firefox).
(4) In the current tab, open the first bookmark that is listed in the bookmark sidebar (when opening the bookmark, a new window will be displayed that asks
the user with which application this bookmark/link shall be opened. Just click
"Cancel").
(5) Create a second tab and open the second bookmark in it (again click "Cancel").
(6) Drag-and-drop the second tab into the "display area" so that this tab is
opened in a separate Midori Window.
(7) Drag-and-drop this tab back into the "old" Midori Window so that both tabs
are in one Window again.
(8) In the second tab, open the first bookmark and after that open
the second bookmark again.
(9) Midori crashes.

Bookmarks file

The two special bookmarks from firefox.

Comment 17 Kevin Fenzi 2016-02-08 13:37:16 UTC
Would you be willing to fix this upstream ( https://launchpad.net/midori ) or would you like me to do so? There's a few other similar known bookmark import bugs, but not this specific one...

Comment 18 Fedora End Of Life 2016-11-24 15:25:51 UTC
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 19 Fedora End Of Life 2016-12-20 18:29:58 UTC
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
