Bug#280516: scrollkeeper-update segfaults, causing dpkg to fail

[Rob Speer]

Package: scrollkeeper
Version: 0.3.14-9.1
Severity: grave
Justification: renders package unusable

Currently, packages that use scrollkeeper are failing to update in dpkg,
because scrollkeeper-update consistently segfaults.

I tried reinstalling scrollkeeper, and it segfaulted at the point where
scrollkeeper-rebuilddb runs scrollkeeper-update.

The gdb backtrace looks like this:

#0  0x4007e256 in __xmlRaiseError () from /usr/lib/libxml2.so.2

...

As a temporary workaround, I have made /usr/bin/scrollkeeper-update a link to
/bin/true. That makes dpkg happy.
