Package: libgdk-pixbuf2
Version: 0.22.0-11
Severity: important
Running a program that uses gdkpixbuf (in this case, freeciv 2.1) under
valgrind reveals numerous memory errors. These all happen inside
_gdk_pixbuf_load_module. For instance:

In this case the malloc simply isn't big enough, or perhaps the read is in
the wrong place. This is a bizarre and fairly serious error, I suspect.
I don't really know that this error is caused by gdkpixbuf; it could be
directly within the dl code. However the dl functions do not have symbol
information it seems, and I don't know why (I have libc6-dbg installed).

Thanks for checking, I’m closing the bug.
