Bug#702780: GdkPixbuf:ERROR:gdk-pixbuf-animation.c:242:gdk_pixbuf_animation_new_from_file: assertion failed: (animation)

[Vincent Danjean]

Package: libgdk-pixbuf2.0-0
Version: 2.27.2-1
Severity: important
Tags: upstream

  Hi,

  While trying to run wicd-gtk with libgdk-pixbuf2.0-0 from experimental,
I got a assertion fail. Running under gdb with -dbg packages, I got the
backtrace copy-pasted at the end of this message.
  I recompiled libgdk-pixbuf2.0-0 with a patch that revert the upstream
commit 9201fcfdcafd865bc10624c5c3a12192b5eeea9a "animation: Improve error
handling".
  This fixed the problem for me (ie wicd-gtk works perfectly again now).

  I do not know if the real bug is this commit or an bad use of
libgdk-pixbuf2.0-0 by wicd.
  Note that a similar symptome is described in 702517 that uses the same
version of libgdk-pixbuf2.0-0 (according to the bug report). I did not checked
if my workaround also work for this bug.

  Regards,
    Vincent
