 This probably means that Webkit isn't the problem, but one of the many
libraries it depends upon is.

 Ideally, you should revert everything to the working situation, and then
upgrade the libraries one by one to find the one that is causing the
problem.  Looking at the backtraces, if must be one of gdk, glib, or
uClibc.

 A segmentation fault in free() generally indicates either a double free
or freeing unallocated memory (e.g. a stack variable).  valgrind may help
to pinpoint the problem.
