Strange, I have not seen this before. I am able to open this preference page without problem. Did you try doing "eclipse -clean" ?

I also stumbled upon this:
https://bugzilla.redhat.com/show_bug.cgi?id=1228138
see my comment #9

nope, -clean does not help.

eclipse-platform-4.6.0-0.6.git201605092000.fc24.x86_64

A new version of Egit/Jgit will hit updates-testing soon: https://bodhi.fedoraproject.org/updates/FEDORA-2016-cc924801f2

Please test to see if the issue is still present in the latest version, when it is available.

I've been updates-testing, always am. Inasmuch as the other bug seems to be fixed by:
eclipse-egit-4.4.0-1.fc24.noarch and/or eclipse-jgit-4.4.0-4.fc24.noarch
the problem in Eclipse remains.

Hi,

Is it possible for you to test the Fedora 25 versions of egit/jgit? I would like to know if the problem is still there in F25+

This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. 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bug reports from releases that are no longer maintained.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 '24'.

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 24 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.

Closing due to no response from reporter in six months.
