testembedmoz segfaults

[guest]

Yesterday after a long time I built fedora's gtk2hs with mozembed enabled again since I was curious to play with it.

Then I tried testembedmoz and found that it segfaults at startup.

:
Program received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

The segfault is both on i386 and x86_64 (Fedora 11). I am using ghc-6.10.3 and the latest gtk2hs-0.10.1.

Has anyone had success with mozembed recently?

I have no idea. Since we've moved mozembed out of Gtk2Hs and deprecated it in favour of webkit, I'll leave this bug alone.
