You have been subscribed to a public bug: I tried to use 'gnome-search-tool' to get a list of all of the .svg files on the system. When it finds one, it calls on the gdk_pixbuf loader to get a picture of the .svg file to display in it's list. After installing all of the relevant -dbgsym packages (by hand! there ought to be a tool I can use for that) I ran the search tool like this:
export G_DEBUG=fatal_criticals gnome-search-tool ... which it says to do at: https://wiki.ubuntu.com/DebuggingGNOME ... and then in another console, ran: gdb --pid=$(pidof gnome-search-tool) ... then told it to 'cont' and entered ".svg" into the search box, then selected "File System", and pressed "Search". It runs for a while, and then I get: Program received signal SIGABRT, Aborted.

gsearchtool.c:3187 Hmmm... I don't think it's crashing in the same place as before... it's a different file than I recall from the time I ran it and did not take notes. (running it again from the start to see....) Ok, it is the same every time, but maybe how many times it keeps going past a critical error is when it crashes so if you don't have the same set of files installed it might bomb at a different one? I have no familiarity with that software's internals, so I can't fix it. ** Affects: libcairo (Ubuntu) Importance: Undecided Status: Unconfirmed -- svg_loader.so fails reading svg font for 'gnome-search-tool' https://bugs.launchpad.net/bugs/111379 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
