Bug Description

When a plugin fails to load from the normal plugin directories, like so:

/home/smspillaz/Applications/Compiz/bin/compiz (core) - Debug: Trying to load move from: /home/smspillaz/Applications/Compiz/lib/compiz/libmove.so
/home/smspillaz/Applications/Compiz/bin/compiz (core) - Debug: dlopen failed: /home/smspillaz/Applications/Compiz/lib/compiz/libmove.so: undefined symbol: _ZN18PluginClassHandlerI8GLWindow10CompWindowLi8EE3getEPS1_

/home/smspillaz/Applications/Compiz/bin/compiz (core) - Debug: Opened library: libmove.so

We end up with a crash like this:

The reason appears to be that we're loading from the system library paths, but that doesn't make any sense.

This bug was fixed in the package compiz - 1:0.9.10+13.10.20130822-0ubuntu1

---------------
compiz (1:0.9.10+13.10.20130822-0ubuntu1) saucy; urgency=low

  [ Sam Spilsbury ]
  * Bump version to 0.9.10

  [ Łukasz 'sil2100' Zemczak ]
  * Remove debian/patches/unity_support_test.patch:
    - Running the support test from compiz has bad side effects, from now
      on we run it from Xsession.d
  * Automatic snapshot from revision 3644

  [ Iven Hsu ]
  * Opacify: Only dim the windows above the active window.(LP:
    #1189374). (LP: #1189374)
  * KWD: Fix compile errors with KDE 4.11. The KWin developers made
    kdecorationbridge.h private. See:
    http://lists.freedesktop.org/archives/compiz/2013-March/003479.html
    (LP: #1193792). (LP: #1193792)

  [ Nikolay Martynov ]
  * When static switcher is enabled and has an option to show
    application icon turned on the icons are expected to be ~1/3 of a
    thumbnail (48px). Instead they are displayed in 512px size and
    completely cover everything. This change addresses this issue. See
    LP #1173914. (LP: #1173914, #1186426)

  [ BryanFRitt ]
  * Fixed the non-working Annotate 'Clear' Button. Moved this option's
    CCSM position upwards to keep the button shortcuts together. (LP:
    #1202907). (LP: #1202907)

  [ Mehrdad Afshari ]
  * Added "move window to previous monitor" feature to compiz Put
    plugin. (LP: #1178581)

  [ Hu Kang ]
  * gtk-window-decorator: destroy action menu when any of the (close,
    min, max) buttons on the title bar is pressed. (LP: #1101648)
  * Remove redundant src/logmessage/include/core/logmessage.h (LP:
    #1067246). (LP: #1067246)

  [ Steve Langasek ]
  * Fix for bug #763148 (with added test cases): when the desktop is
    resized, windows should stay on their original workspace. (LP:
    #763148)

  [ Brandon Schaefer ]
  * Unrevert 3728, fix failing tests. Change the behaviour of
    undecorating windows. Previously when a window was undecorated, we
    would shift it back to an appropriate position according to its
    gravity member. That behaviour was problematic because in the
    StaticGravity case the window has to just stay in the same place.
    But then if you had a window with StaticGravity which then did get a
    decoration and later removed it, it would be placed as though it was
    decorated and appear to be in the wrong place. The correct behaviour
    is to place all windows as though they have decorations, and then
    when decorations are removed, to move the window back to the corner
    as indicated in its gravity and then expand its size to cover the
    obscured regions no longer hidden because the decorations went away.
    (LP: #1165343).   1. Completely remove decorOffsetMove and other
    related code from      decor.cpp. Put the logic to handle the
    window->input () - window->border ()      placement offset inside of
    setWindowFrameExtents instead. Now the window      will always be
    offset from its original non-decorated position to the new
         decorated position, rather than having to guess between
    decoration sizes.   2. Make saveGeometry and restoreGeometry work
    relative to window->border ()      a...
