I have also check for the bzr whoami it display well date, also i have done the login on the launchpad using
bzr launchpad-login

when i try to run the `bzr visualise` it display the date in good format, but the problem is it will not display the revision difference and generating the error in log file looks like

This has been fixed in recent versions of bzr-gtk.

If you don't want to upgrade bzr and bzr-gtk from sources,
you can add https://edge.launchpad.net/~bzr/+archive to your software sources
(follow the link for instructions).

Let us know if that fixes your problem.

Hello, are you sure this is fixed?

I have the latest packages from your PPA and I'm still getting the error:

Am I doing something wrong?

I don't think the PPA has a very recent version of bzr-gtk packaged.

I have the same error with bzr-gtk version 0.97.0 from Debian unstable
in line 111 of file /usr/share/pyshared/bzrlib/plugins/gtk/diff.py

The problem is due to the gedit style scheme placed in the directory
~/.gnome2/gedit/styles/ by the gedit preferences gui (Add button).
This directory is not searched by gtksourceview2.StyleSchemeManager().get_scheme().
As the Style Scheme is not found, "None" is assigned to style_scheme and
it is passed to buf.set_style_scheme(style_scheme) giving the error.

So I think there are at least two corrections needed:

1. Add local gedit styles directory in the search path with:
  gtksourceview2.StyleSchemeManager.append_search_path('~/.gnome2/gedit/styles')
  before calling get_scheme().

2. Add a condition to check if style_scheme is not None before line 111
   in file diff.py to avoid other possible unexpected similar errors.

In the mean time there is a workaround for users. Simply move (or copy or link)
the style scheme file (.xml) used from ~/.gnome2/gedit/styles/ into
~/.local/share/gtksourceview-2.0/styles/

Also, I am not sure to fully understand the logic in file diff.py lines 80-82
where probably another condition is needed to check if a scheme style was set
with apply_gedit_colors() before calling apply_colordiff_colors(),
because, as it is now, any change done with apply_gedit_colors() is superseeded
by apply_colordiff_colors() unconditionally.

[Cyberkilla (cyberkilla04uk-deactivatedaccount)]

Wow, so in other words, it is only a problem if you are using a custom theme for gedit?

I created gtksourceview-2.0/styles and copied over the custom themes just to test - it worked. I then chose one of the default themes and that worked too.

Thanks a lot! I've been waiting for weeks to get a solution to this problem. I'm glad *somebody* can be seen to give a damn.

[Edward Ari Bichetero (ebichete)]

Changed status to "Confirmed" because bug still exists in trunk and 10.04 "Lucid" (0.98.0.final.1). Have attached a branch with the fix (https://code.launchpad.net/~ebichete/bzr-gtk/bugfix_lp429947). The logic from the fix comes from jras in comment 11 above.
