Package: inkscape
Version: 0.43-5
Severity: grave
Justification: renders package unusable
Steps to reproduce (/tmp/home used to make sure nothing in $HOME can affect
this):
1) mkdir /tmp/home
2) cp ~/.Xauthority /tmp/home
3) HOME=/tmp/home strace -o inkscape.strace -f -s4096 inkscape
Expected results:
3) inkscape should start and show a window.
Actual results:
3) Inkscape prints the following error message and neither exits nor
opens a window.
Entity: line 3: parser error : Input is not proper UTF-8, indicate encoding !
Bytes: 0x90 0xE7 0x65 0x08
<id>org.inkscape.input.gdkpixbuf.ion>. ^
Entity: line 8: parser error : PCDATA invalid Char value 8
<filetypetooltip>t</filetypetooltip>
^

2) The erroneous XML fragment is probably generated in
../src/extension/internal/gdkpixbuf-input.cpp line 134
gchar *xmlString = g_strdup_printf(
"<inkscape-extension>\n"
"<name>%s GDK pixbuf Input</name>\n"
"<id>org.inkscape.input.gdkpixbuf.%s</id>\n"
"<input>\n"
"<extension>.%s</extension>\n"
"<mimetype>%s</mimetype>\n"
"<filetypename>%s (*.%s)</filetypename>\n"
"<filetypetooltip>%s</filetypetooltip>\n"
"</input>\n"
"</inkscape-extension>",
name,
extensions[i],
extensions[i],
mimetypes[j],
name,
extensions[i],
description
);
where apparently
extensions[i] = "\220\347e\10"
mimetypes[j] = "\260\347e\10"
name = "gif"
description = "\230te\10"
3) I copied the function in gdkpixbuf-input.cpp to a standalone
program (attached as gdkpixbuf-input.cpp) but does not seem to
reproduce the problem:
$ g++ -o gdkpixbuf-input gdkpixbuf-input.cpp `pkg-config gdk-2.0 --cflags
--libs`
$ ./gdkpixbuf-input | grep gif
<name>gif GDK pixbuf Input</name>
<id>org.inkscape.input.gdkpixbuf.gif</id>
<extension>.gif</extension>
<mimetype>image/gif</mimetype>
<filetypename>gif (*.gif)</filetypename>
4) I built inkscape with debugging symbols using
$ time DEB_BUILD_OPTIONS="nostrip debug noopt" fakeroot apt-get --build source
inkscape
$ sudo dpkg -i inkscape*.deb
and now inkscape fails differently!
$ HOME=/tmp/home inkscape
inkscape: gconv_dl.c:166: do_release_shlib: Assertion `obj->counter > 0' failed.
Emergency save activated!
** (process:22423): ERROR (recursed) **: file inkscape.cpp: line 781

5) GDB suggests that the problematic code in gdkpixbuf-input.cpp is
never reached with the debugging build:
