In the end, we overcame the problem by using SUSE as our mingw cross
compiling environment instead of Fedora.
I'm not sure if the patches included in the SUSE mingw32-libwebkit
package fixed a bug, or if the root cause of the problem was something
to do with Fedora's mingw environment. I just know that we aren't
getting the seg fault when compiling in SUSE.
Hope this helps anyone experiencing a similar problem.
