This bug also affects strigi which unfortunately uses libxml2 too. This causes
applications that depend on strigi to crash too (like dolphin from kde4). In
dolphin, if you try to mouseover any file, it crashes with the following
backtrace:
Application: Dolphin (dolphin), signal SIGSEGV

The wierd thing about this backtrace is that after I installed libxml2-dbg to
get a better backtrace, the backtrace changed and libxml2 doesn't show up
anymore... plus that it now crashes with SIGABRT. Here are the first stack
frames (the rest is like before):

Anyway, I am sure libxml2 is the problem because downgrading libxml2 to
2.6.32.dfsg-2 solves the problem.
