Python indent mode doesn't unindent pass correctly with tabs

Binary package hint: kate

I am using Kubuntu 6.10 amd64 with KDE 3.5.5 and Kate 2.5.5 (package version 3.5.5-0ubuntu3). When using Python indentation and tabs, Kate doesn't unindent the "pass" statement correctly.

1. Create a new document (File -> New). This must be done first, as Kate does not automatically apply indentation settings to new files. I will file a separate bug report for this shortly.

2. Go to Settings -> Configure Kate -> Editor -> Indentation and configure things as follows:

    Automatic Indentation:
        Indentation mode: Python Style (may be overridden by filetype)
    Indentation with Spaces:
        Use spaces instead of tabs to indent: Off (unchecked)

3. Type the following (note that the words in <angled brackets> are keys you should press, and should not be typed verbatim):

    class asdf: <return>
    pass <return>

After pressing <return> the first time, a tab is inserted at the beginning of the next line. After the second time pressing <return> (after "pass"), the correct behavior would be to remove the tab and leave the following line unindented. Instead, Kate indents the next line with a single space. I have tried this more tabs and it converted each tab into a space on the following line, but I have been unable to reliably reproduce the effect with multiple tabs.
