This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug. If you can, give
a recipe starting from `emacs -Q':
This is with -Q:
(require 'xml)
(defun tzz-image-from-svg-string (width height unread unseen)
(with-temp-buffer
(let* ((svg-data (tzz-make-ungradient width height unread unseen))
(image (create-image svg-data 'svg t :ascent 'center))
(props `(display ,image intangible ,image)))
(insert "i")
(add-text-properties (point-min) (point-max) props)
(buffer-string))))
(defun tzz-make-ungradient (width height unread unseen)
"Return svg describing the UNREAD/UNSEEN ratio graphically.
WIDTH HEIGHT sets the box size."
(with-temp-buffer
(xml-print
`((svg
((xmlns:xlink . "http://www.w3.org/1999/xlink")
(xmlns . "http://www.w3.org/2000/svg")
(width . "200")
(height . "200"))
(defs ()
(linearGradient
((id . "linearGradient2")
(xlink:href . "#linearGradient2"))))
(g ()
(rect ((width . "100%")
(height . "100%")
(style . "fill:url(#linearGradient2)"))))
)))
(buffer-string)))
;; works fine
(tzz-make-ungradient 200 70 100 80)
;; locks up Emacs
(insert (tzz-image-from-svg-string 96 12 200 30))
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/local/share/emacs/23.1.91/etc/DEBUG.

The bug you reported appears to be a librsvg bug. To see this, create
an svg image with the following contents:
<svg xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns="http://www.w3.org/2000/svg" width="200" height="200">
<defs>
<linearGradient id="linearGradient2" xlink:href="#linearGradient2"/>
</defs>
<g>
<rect width="100%" height="100%" style="fill:url(#linearGradient2)"/>
</g>
</svg>
Any librsvg-based application that tries to open this file should lock
up. I've tested with gqview and eog. I have filed this bug in the
Gnome Bugzilla (Bug 608575):
http://bugzilla.gnome.org/show_bug.cgi?id=608575
I will close this in the Emacs bug database, since it is not an Emacs
bug per se. Thanks.

Should Emacs lock up hard (C-g doesn't work) though? Maybe the librsvg
process can be interrupted after 10 seconds if it hasn't returned?
Sorry for my ignorance, I don't know enough about the internals.
