GNOME Bugzilla – Bug 591766
librsvg 2.26.0 and its gdk loader crashes, derived programs either don't display SVG files or segfault
Last modified: 2011-11-09 20:15:08 UTC
Steps to reproduce: 1. Trying to run any program that depends on librsvg library (triggers the "cannot display" case) 2. Trying to open SVG file with rsvg-view (which displays it correctly) and then save it (which crashes it with a segmentation fault) Stack trace: Replication of "rsvg-view crashes" condition: root [ ~ ]# gdb /usr/bin/rsvg-view GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Created attachment 141695 [details] [review] patch
Thank you, this did solve the problem with crashing rsvg-view. Still, the more serious issue remains; namely, that with librsvg's GDK pixbuf loader, which still does not work (for example, SVG icons are not loaded, with standard error message "Error loading theme icon 'foo-bar' for stock: Unrecognized image file format"). Even more so, I do not know how to trace something like GDK loader which is being run only indirectly + (AFAIK) on demand, and usually does not cause the main program to crash/throw an exception, nor is it being loaded at program's startup, where I could use GDB's shared symbol autoloading facilities. Thanks in advance.
Comment on attachment 141695 [details] [review] patch Committed with configure.in change.
Arets, please attach the problem svg file here. The link in comment #1 has been death.
The test-display and rsvg-view are working correctly now, although GTK loader for SVG still fails and issues error about "Unrecognized image file format". Is there any plausible way to debug the loader itself?
EOG will suit it. Anyway please attach the file.
Sometimes, SVGs have a large GPL/header license at the top. The loader is looking for an "<svg" tag in the file's first N bytes. If it doesn't find that, then it will say "I don't know how to load this type of image."
The "svg-viewer.svg" file I previously uploaded can actually be found in the librsvg source distribution, in the 'data' subfolder. This is what I used to examine the failures, I just forgot to mention it. And, no, the presence or absence of disclaimer seems to be no issue in this case; the SVG loader (located in the standard location, i.e., /usr/lib/gtk-2.0/2.10.0/loaders/svg_loader.so) fails to provide any image data for any SVG file. With EOG, do you mean Eye of Gnome? If so, what relevance it has regarding the debugging possibilities of the loader, or did I just misunderstand something?
(In reply to comment #10) > With EOG, do you mean Eye of Gnome? If so, what relevance it has regarding the > debugging possibilities of the loader, or did I just misunderstand something? Because EOG uses the svg loader through GdkPixbufLoader. So if the svg loader is correctly loaded, you can see symbols of the svg loader and librsvg itself in gdb.
Works here with librsvg git master, both in the pixbuf loader test, and eog.

'... any... for any SVG file' means there's a local installation problem on your machine.
