Bug Description

Clicked on this link:

It opened in Document Viewer (evince). At the same time I got this compiz error and the window border was missing (not anymore, something gtk-window-decorator (not compiz), it seems, got restarted).

This compiz error happened previously, under I think the same situation (opening (another) PDF file, but then with the provided kernel. ATM I'm running oneiric kernel).

Hope this helps. This is my first Ubuntu bug report.

[I checked "reproducible" checkbox because this happened before, but on second thought I deleted "reproducible" from the optional tags. I'm guessing that reverts my decision. I tried clicking the link again and this did not happen again so it seems to be kind of random.]

Looks like a simple crash to avoid. Both functions at the top of the stack are being called with a NULL pointer.

max_window_name_width (win=0x0) at /build/buildd/compiz-
update_window_decoration_size (win=0x0) at /build/buildd/compiz-

I do wonder why we didn't ever see this before though.

I have had three crashes that I suspect are inter-related.
I just filed bugs on banf and nautilus, and then re-booted and this crash happened. In the earlier bugs also the window shaper was affected.
I hope the other bugs contain good information; if not, they can probably be considered duplicates of this one.

This happenned to me on the following situation:
1. Installed Moneydance on 64-bit ubuntu with official jre (ln -s /opt/jre1.6....... /opt/moneydance/jre) from (available as a trial version which is the same as real version but limitted data entry until unlocked). OpenJDK btw doesn't work well with this when it comes to installing extensions, and the 32-bit jre that came with it doesn't work on 64-bit ubuntu apparently, i had to manually download 64-bit jre and copy it to /opt.
2. Ran moneydance, it ran fine
3. I pinned moneydance ("lock to launcher")
4. I then tried running it from launcher and this happenned

Note, this program apparently can't run from being locked in launcher, probably because of the way it's a java program and launches from a script, if i go to command prompt and type 'moneydance' ... I probably have to manually create a .desktop file for it to launch it.

This could be because i clicked to launch a window and the window never launched and the window manager never found it, perhaps?

compiz (1: precise-proposed; urgency=low

  [ Łukasz 'sil2100' Zemczak ]

    - Finish the implementation of the locally integrated menubars
      (LP: #931245)
    - Unity/compiz intercepts keystrokes from grabbed windows (LP: #806255)
    - Pressing alt doesn't show the menu title bar in top panel (LP: #943194)
    - Fix Alt stealing focus from widgets (LP: #943851)
    - Fix Alt + drag (LP: #945373)
    - lp:compiz-core fails parallel builds (make -jN) (LP: #938417)
    - Changing the HUD shortcut disables all Alt-based combinations. And
      changing the Dash shortcut disables all Super-based shortcuts
      (LP: #945816)
    - Fix key bindings (such as Super) not working on empty workspace or on
      slow/loaded systems (LP: #953089)
    - compiz crashed with signal 5 in Glib::exception_handlers_invoke()
      (LP: #808007)
    - Fix segfault caused by r3043 (LP: #958540)
  * Removed cherry-picked patches:

  [ Didier Roche ]
  * pick upstream fix, debian/patches/fix_953839.patch:
    [regression] Invisible resize border is now only 1px wide (LP: #953839)
  * debian/patches/revert_lim.patch:
    - revert the integrated menu patch. It won't be released in precise and
      triggers a regression (in bug #962085)
  * debian/patches/fix_953089_2.patch:
    - second trial to fix remaining corner cases
  * debian/patches/exit_1_if_composite_cant_init.patch:
    - try to workaround a crasher which seems to happen when the composite
      plugin failed to initialize. Hopefully exiting 1 will make gnome-session
      respawning compiz and then the init will work. (LP: #833729)
  * debian/patches/always_replace.patch:
    - right now, always replace the current WM as it seems that some people
      got another compositor running at the start of the session. This will
      hopefully workaround the issue that some people experience.

Crashed by fullscreen mode of Adobe Acrobat Reader 9.4.7 and Google Earth.

The program 'gtk-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 12302 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
