Steps to reproduce in a fully updated F18 alpha:

1. Build WebKitGtk via the build script using installed/system libraries
2. Launch WebKitBuild/Release/Programs/GtkLauncher

Expected results: No segfault
Actual results: Segfaults reliably upon launch 100% of the time

(Might be some weird F18 thing, but just in case....)

Full backtrace attached.
