[j s n j]

This also applies to v0.0.3 on my 13.04. I've been asked to report a bug. Not sure if it's a duplicate. Here's the terminal output when start is attempted.

also in 12.10 with 0.0.4-0~92~quantal1

[J Phani Mahesh (phanimahesh)]

A fix has been committed to silently disable ('grey-out') the troubling settings if the schemas are not installed.

Can you please verify if 0.0.4-0~97~quantal1 solves this issue? (This package is currently queued for building and should be available via the PPA lp:freyja-dev/unity-tweak-tool-daily in an hour. )

[Sylvain BROCHAND (sbrochand)]

With 0.0.4-0~97 on 12.10, the error message becomes :

Yes. Pretty much the same in 97

We have triggered a build without alowing launchpad to update the bzr repository and as a result, the package got built without the fixes. Apologies for the inconvenience.

Please wait a few hours for 0.0.4-0~99 to be available from the PPA.

Status changed to inprogress till a user confirms that the bug is fully fixed.

This was reported as a seperate bug few hours ago and a fix has been
committed. This was a direct consequence of my patch yesterday which
overlooked certain aspects. Apologies for the inconvenience.
Please wait a few hours for the PPA to update and verify if the bug is
fully resolved with the next update. (v~102)

Can you attach the file "~/.config/unity-tweak-tool/debug.log" ?

It is a work-in-progress of a extremely verbose logging system but in
this case I believe it might hold some information of value.

Open the application, and once it crashes, locate the file and add it
as a bug attachment.

[J Phani Mahesh (phanimahesh)]

Thanks for the debug log. It helped.

Can you
 - download the latest snapshot from
https://github.com/phanimahesh/unity-tweak-tool/archive/rewrite.zip
 - Extract it somewhere, eg : ~/unity-tweak-tool (~ is your Home
directory)
 - open a terminal, and run the following commands
     cd ~/unity-tweak-tool
     python3 develtest.py

If it gives a permission error, run
     chmod +x develtest.py
     chmod +x unity-tweak-tool
and then
     python3 develtest.py

It opens Unity-Tweak-Tool running the snapshot you just downloaded. I
am positively sure that the bug is fixed in my last commit. Please
confirm.

(Ignore if certain icons on the overview tab appear missing. That can
happen if you run the development version without installing utt, and
is not a bug. )

Terminal output from the downloaded rewrite. Also, attached is copy of debug info from this attempt.

[J Phani Mahesh (phanimahesh)]

That looks unusual to me. I have removed overlay-scrollbar package to
force the application to crash. The application crashes with the version
in the PPA but does not crash with the development snapshot.

It is possible that the installed version is interfering somehow. Please
allow the PPA to update, then update your system, and see if the problem
persists. Alternately, you can uninstall unity-tweak-tool and then try
running the development snapshot.

Thank you for your co-operation and apologies for the inconvenience. If
you would like a quick workaround, installing overlay-scrollbar package
should allow the application to open normally without crashing.
