Bug#751170: yelp: Crashes when clicking on a HTML link pointing to an anchor

[intrigeri at debian.org]

Package: yelp
Version: 3.4.2-1
Severity: important
Tags: fixed-upstream
Control: forwarded -1 https://bugzilla.gnome.org/show_bug.cgi?id=686095

Hi,

on Wheezy, when browsing a HTML document in Yelp, and clicking on
a link that points to an anchor, Yelp crashes. This can be reproduced
with the attached document:

  $ yelp file:///absolute/path/to/sysadmin.html

... then click on "Read this first", and boom:

  (yelp:3933): GLib-ERROR **:
  /tmp/buildd/glib2.0-2.33.12+really2.32.4/./glib/gmem.c:165: failed
  to allocate 18446744073709538726 bytes
  Trace/breakpoint trap

We (Tails developers) reported this bug upstream, and had a fix merged
a while ago (commit b617a61), which has been released as part of Yelp
3.8.0. Sadly, we apparently forgot to get the fix into Wheezy :(

With this patch applied, Yelp doesn't crash anymore. Still, things are
not very good either: clicking an anchor link opens Nautilus (who
knows why), but double-clicking it works fine. I'll report this
separately, as testing/sid are also affected. That's why I'm not
proposing to take this to the release team for a stable update.

FWIW, I'm attaching the patch we might apply in Tails/Wheezy.

Cheers,
