[Pkg-gmagick-im-team] Bug#533704: imagemagick: identify crashes on non-image XML files

[Justin B Rye]

Package: imagemagick
Version: 7:6.3.7.9.dfsg2-1
Severity: minor

(Also found in Lenny's 7:6.3.7.9.dfsg2-1~lenny1.)

Running "identify *" on a directory that contains non-imagefiles
can't be expected to work well, but I was expecting "no decode
delegate for this image format", not this:

 (process:3100): GLib-GObject-WARNING **: invalid unclassed pointer in cast to `GObject'

 (process:3100): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
 identify: Memory allocation failed `eg.rdf'.

The above happens with any RDF file, while XHTML gives me:

 (process:3111): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
 This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
 The overwriting error message was: Error parsing XML data

 identify: Memory allocation failed `eg.html'.

There's an obvious workaround ("don't do that then"), so I'm only
calling it "minor"; but it claims it's buggy, and who am I to argue?
With imagemagick-dbg I don't get the WARNING messages, just:

 identify: Memory allocation failed `eg.rdf' @ svg.c/ReadSVGImage/2827.

 identify: Memory allocation failed `eg.html' @ svg.c/ReadSVGImage/2827.

Looks like for a start it's seeing all XML as SVG...
