           Summary: konsolepart aborting with assert() when displaying
                    utf8-testfile
           Product: konsole
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: seife at opensuse.org


Version:           Version 2.4 - KDE 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2)) "release
214" (using Devel)
OS:                Linux
Installed from:    Compiled sources

konsolepart crashes when displaying the diff of busybox 1.16.0 to current git
in a pager (less) or vim.

I'll attach a testfile, that, when viewed with less, crashes konsole. (jump to
the end and scroll a few pages up to trigger the crash quickly).

Yakuake crashes in exactly the same way, so it's probably a konsolepart
problem.

The triggered assert() is:

konsole: ../3rdparty/harfbuzz/src/harfbuzz-shaper.cpp:436: void
HB_HeuristicSetGlyphAttributes(HB_ShaperItem*): Assertion `item->num_glyphs <=
length' failed.
